Maria Theresa Thaler
The Maria Theresa thaler (MTT) is a silver bullion coin and a type of Conventionsthaler that has been used in world trade continuously since it was first minted in 1741. It is named after Maria Theresa who ruled Austria, Hungary, Croatia and Bohemia from 1740 to 1780 and is depicted on the coin. History In 1741, the first MTT was struck according to the standard with of a Cologne mark of fine silver, or 25.98 grams. In 1750 a new thaler was struck with a gross weight of of 1 Vienna mark of silver, fine (with a fine silver content of 23.39 grams, or of a Cologne mark). In 1751 this new standard was effectively adopted across the German-speaking world when it was accepted formally in the Bavarian monetary convention. This new, post-1751 thaler has continued as a trade coin ever since. Since the death of Maria Theresa in 1780, the coin has always been dated 1780. On 19 September 1857, Emperor Francis Joseph of Austria declared the Maria Theresa thaler to be an official t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Muscat And Oman
The Sultanate of Muscat and Oman (), also known briefly as the State of Muscat and Oman () during the rule of Taimur bin Feisal, was a sovereign state that encompassed the present-day Sultanate of Oman and parts of present-day United Arab Emirates and Pakistan, in the second half of the 19th century and 20th century. Ruled by the Busaid dynasty, it was established as a result of the partition of the Omani Empire upon the death of its last ruler Said bin Sultan. The Sultanate transitioned into a new form of government after the palace coup of 23 July 1970 in which the sultan Said bin Taimur was immediately deposed in favor of his son Qaboos bin Said. Name Strictly speaking, Oman (Imamate of Oman, , ʿUmān al-Wusṭā) is the inner, continental part of the region without access to the coast and with the capital in the city of Nizwa. Muscat is a coastal sultanate, the rulers of which, in fact, carried out expansion, including overseas. Historical Muscat and Oman ar ...

Millesimal Fineness
The fineness of a precious metal object (coin, bar, jewelry, etc.) represents the weight of ''fine metal'' therein, in proportion to the total weight which includes alloying base metals and any impurities. Alloy metals are added to increase hardness and durability of coins and jewelry, alter colors, decrease the cost per weight, or avoid the cost of high-purity refinement. For example, copper is added to the precious metal silver to make a more durable alloy for use in coins, housewares and jewelry. Coin silver, which was used for making silver coins in the past, contains 90% silver and 10% copper, by mass. Sterling silver contains 92.5% silver and 7.5% of other metals, usually copper, by mass. Various ways of expressing fineness have been used and two remain in common use: ''millesimal fineness'' expressed in units of parts per 1,000 and '' karats'' or ''carats'' used only for gold. Karats measure the parts per 24, so that 18 karat = = 75% gold and 24 karat gold is considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Troy Weight
Troy weight is a system of units of mass that originated in the Kingdom of England in the 15th century and is primarily used in the precious metals industry. The troy weight units are the grain, the pennyweight (24 grains), the troy ounce (20 pennyweights), and the troy pound (12 troy ounces). The troy grain is equal to the grain unit of the avoirdupois system, but the troy ounce is heavier than the avoirdupois ounce, and the troy pound is lighter than the avoirdupois pound. Legally, one troy ounce (oz t) equals exactly 31.1034768 grams. Etymology Troy weight is generally supposed to take its name from the French market town of Troyes where English merchants traded at least as early as the early 9th century. The name ''troy'' is first attested in 1390, describing the weight of a platter, in an account of the travels in Europe of the Earl of Derby. Charles Moore Watson (1844–1916) proposes an alternative etymology: ''The Assize of Weights and Measures'' (also known a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proof Coinage
Proof coinage refers to special early samples of a coin issue, historically made for checking the die (manufacturing), dies (as in demonstrating that something is true) and for archival purposes. In modern times, proofs are often struck in greater numbers, especially for coin collecting, coin collectors (numismatists). Nearly all countries have issued proof coinage. Preparation of a proof striking usually involved polishing of the dies. They can usually be distinguished from normal circulation coins by their sharper rims and design, as well as much smoother "fields"— the blank areas not part of the coin's design. The dies for making modern proof coins are often treated with chemicals to make certain parts of the design take on a frosted appearance, with the polished fields taking on a mirror finish. Several other methods have been used in the past to achieve this effect, including sand blasting the dies, and matte proofs. Proof coins of the early 19th century even appear to b ...

Austrian Mint
The Austrian Mint () is located in Vienna and is responsible for minting Austrian coins. Since 1989 it has been a public limited company (''Aktiengesellschaft'') and a subsidiary of Austria's central bank Oesterreichische Nationalbank, which also has its headquarters in Vienna. The Austrian Mint carries out both the design and stamping of the coins it produces. Until 2002 it was only responsible for minting the coins of the Austrian schilling; since then it has been responsible for producing the Austrian euro coins. The mint also produces other coins, such as gold bullion coins, as well as commemorative issues: the Vienna Philharmonic coins and the Maria Theresa thaler are produced by the Austrian mint, for example. The mint also supplies circulation coins and blanks to many other countries across the world. In addition to gold coins, the Austrian mint also produces silver coins, platinum coins, as well as bullions in various sizes. History In 1194, Duke Leopold V of Aust ...

German Orthographic Conference Of 1901
The German Orthographic Conference of 1901 (the Berlin II Orthographic Conference; or ) was a conference of orthography that took place in Berlin 17–19 June 1901. The results of the conference became official in the German Empire in 1902.Edited by Werner Besch, Anne Betten, Oskar Reichmann, Stefan Sonderegger: ''Sprachgeschichte: Ein Handbuch zur Geschichte der deutschen Sprache und ihrer Erforschung – 2., vollständig neu bearbeitete und erweiterte Auflage – 3. Teilband'' (''Hanbücher zur Sprach- und Kommunikationswissenschaft'', Band 2.3), Walter de Gruyter, 2003, p. 2495 (chapter "Geschichte der Interpunktionssysteme im Deutschen"). The standardized German spelling that resulted from the conference was largely based on the Prussian school spelling, but also on the Orthographic Conference of 1876. The conference results removed numerous existing variant forms.Soon after the conference, its results were criticized by people who believed there should be further changes. ...

Popular Science
Popular science (also called pop-science or popsci) is an interpretation of science intended for a general audience. While science journalism focuses on recent scientific developments, popular science is more broad ranging. It may be written by professional science journalists or by scientists themselves. It is presented in many forms, including books, film and television documentaries, magazine articles, and web pages. History Before the modern specialization and professionalization of science, there was often little distinction between "science" and "popular science", and works intended to share scientific knowledge with a general reader existed as far back as Greek and Roman antiquity. Without these popular works, much of the scientific knowledge of the era might have been lost. For example, none of the original works of the Greek astronomer Eudoxus (4th century BC) have survived, but his contributions were largely preserved due to the didactic poem '' Phenomena'' writte ...

Office Of Strategic Services
The Office of Strategic Services (OSS) was the first intelligence agency of the United States, formed during World War II. The OSS was formed as an agency of the Joint Chiefs of Staff (JCS) to coordinate espionage activities behind enemy lines for all branches of the United States Armed Forces. Other OSS functions included the use of propaganda, subversion, and post-war planning. The OSS was dissolved a month after the end of the war. Intelligence tasks were shortly later resumed and carried over by its successors, the Strategic Services Unit (SSU), the United States Department of State, Department of State's Bureau of Intelligence and Research (INR), and the Central Intelligence Group (CIG), the intermediary precursor to the independent Central Intelligence Agency (CIA). On December 14, 2016, the organization was collectively honored with a Congressional Gold Medal. Origin Before the OSS, the various departments of the executive branch, including the United States Departm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Occupation Of The Dutch East Indies
The Empire of Japan occupied the Dutch East Indies (now Indonesia) during World War II from March 1942 until after the end of the war in September 1945. In May 1940, Germany German invasion of the Netherlands, occupied the Netherlands, and martial law was declared in the Dutch East Indies. Following the failure of negotiations between the Dutch authorities and the Japanese, Japanese assets in the archipelago were frozen. The Dutch declared war on Japan following the 7 December 1941 attack on Pearl Harbor. The Japanese invasion of the Dutch East Indies began on 10 January 1942, and the Imperial Japanese Army overran the entire colony in less than three months. The Dutch surrendered on 8 March. Initially, most Indonesians welcomed the Japanese as liberators from their Dutch colonial masters. The sentiment changed, however, as between 4 and 10 million Indonesians were recruited as forced labourers (''romusha'') on economic development and defense projects in Java. Between 200 ...
