Vulcain (watch Company)
Vulcain is a Swiss luxury watchmaker based in La Chaux-de-Fonds, Switzerland. It was founded in 1858 by Maurice Ditisheim as ''Manufacture Ditisheim' in La Chaux-de-Fonds,'' being rebranded as Vulcain in 1894. In 1947, Vulcain developed the first alarm watch, the Vulcain Cricket. Foundation Vulcain was founded in 1858 in La Chaux-de-Fonds, Switzerland by the Ditisheim brothers Maurice, Gaspard and Aron. The Ditisheims were one of many Jewish families involved in innovation and modernisation of the watch industry. Within 20 to 30 years, the company grew from a small studio to a successful and well-known brand. Since the brothers were also involved with foreign branches in the industry, they had the advantage of an international network of contacts. In 1886, Maurice bought the company from his brothers. He was awarded a bronze medal at the Universal Exhibition in Paris 1889 for his self-winding watch "La vallée de l'Arve." Through to the end of the century, the watchmaker ...

Watchmaking
A watchmaker is an artisan who makes and repairs watches. Since a majority of watches are now factory-made, most modern watchmakers only repair watches. However, originally they were master craftsmen who built watches, including all their parts, by hand. Modern watchmakers, when required to repair older watches, for which replacement parts may not be available, must have fabrication skills, and can typically manufacture replacements for many of the parts found in a watch. The term clockmaker refers to an equivalent occupation specializing in clocks. Most practising professional watchmakers service current or recent production watches. They seldom fabricate replacement parts. Instead they obtain and fit factory spare parts applicable to the watch brand being serviced. The majority of modern watchmakers, particularly in Switzerland and other countries in Europe, work directly for the watchmaking industry and may have completed a formal watchmaking degree at a technical school. ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Quartz Crisis
The quartz crisis was the upheaval in the watchmaking industry caused by the advent of quartz watches in the 1970s and early 1980s, that largely replaced mechanical watches around the world.Smithsonian: The quartz revolution revitalized the U.S. watch industry. It caused a significant decline of the Swiss watchmaking industry, which chose to remain focused on traditional mechanical watches, while the majority of the world's watch production shifted to Japanese companies such as , [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phénix
Phénix (French for phoenix) was a small-scale (gross 264/net 233 MWe) prototype fast breeder reactor, located at the Marcoule nuclear site, near Orange, France. It was a pool-type liquid-metal fast breeder reactor cooled with liquid sodium. It generated 590 MW of thermal power, and had a breeding ratio of 1.16 (16% more plutonium produced than consumed), but normally had to be stopped for refueling operations every two months. Phénix continued operating after the closure of the subsequent full-scale prototype Superphénix in 1997. After 2004, its main use was investigation of transmutation of nuclear waste while also generating some electricity. Phénix was shut down in 2009. Construction of Phénix began in November 1968. The first connection to the French national electricity grid was in December 1973. Plans for a French fast reactor date as far back as 1958's ''Rapsodie'', and followed up in 1964 for a larger design with a power output of 1 GWe. Construction ...

History In 1853 Société d' Horlogerie à Waldenbourg was founded as a Swiss watch manufacturing company by the community of Waldenburg, Switzerland. It began to manufacture pocket watcheses in order to create work in the Waldenburg valley whose location at the route Basel-Geneva had become insignificant due to the newly established train connection Basel - Olten - Geneva.

Mountaineering
Mountaineering or alpinism, is a set of outdoor activities that involves ascending tall mountains. Mountaineering-related activities include traditional outdoor climbing, skiing, and traversing via ferratas. Indoor climbing, sport climbing, and bouldering are also considered variants of mountaineering by some. Unlike most sports, mountaineering lacks widely applied formal rules, regulations, and governance; mountaineers adhere to a large variety of techniques and philosophies when climbing mountains. Numerous local alpine clubs support mountaineers by hosting resources and social activities. A federation of alpine clubs, the International Climbing and Mountaineering Federation (UIAA), is the International Olympic Committee-recognized world organization for mountaineering and climbing. The consequences of mountaineering on the natural environment can be seen in terms of individual components of the environment (land relief, soil, vegetation, fauna, and landscape) and location/z ...

14kt Gold
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% and 24 karat gold is considered 100% go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

White House Correspondents' Association
The White House Correspondents' Association (WHCA) is an organization of journalists who cover the White House and the president of the United States.

The WHCA operates independently of the White House. Among the more notable issues handled by the WHCA are the credentialing process, access to the president and physical conditions in the White House press briefing rooms. Its most high-profile activity is the annual White House Correspondents' dinner, which is traditionally attended by the president and covered by the news media.
