picture info	Mining Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

At the time of Anschluss with Nazi Germany in 1938, the Jewish population of Austria was approximately 192,000, mostly in Vienna. Austria had a powerful legacy of Anti-Semitism which found its full expression in Adolf Hitler. in 1895, the Austrian anti-Semite Karl Luger won the majority of the seats in the Vienna municipality and was appointed mayor of the Austrian capital. In 1922, intending to mock vicious anti-semitism in Vienna where Jewish university students were routinely attacked, the Austrian Hugo Bettauer wrote a futuristic novel entitled, The City Without Jews, which turned out to be tr ...
