Following the defeat in World War I, influence of German-speaking elites over Central and Eastern Europe was greatly limited. At the treaty of Versailles Germany was substantially reduced in size. Austria-Hungary was split up. Rump-Austria, which to a certain extent corresponded to the German-speaking areas of Austria-Hungary (a complete split into language groups was impossible due to multi-lingual areas and language-exclaves) adopted the name "German-Austria" (German: Deutschosterreich). The name German-Austria was forbidden by the victorious powers of World War I. Volga Germans living in the Soviet Union were interned in gulags or forcibly relocated during the Second World War.
What name did Rump-Austria adopt?
German-Austria

Many ancient civilizations alloyed metals for purely aesthetic purposes. In ancient Egypt and Mycenae, gold was often alloyed with copper to produce red-gold, or iron to produce a bright burgundy-gold. Gold was often found alloyed with silver or other metals to produce various types of colored gold. These metals were also used to strengthen each other, for more practical purposes. Copper was often added to silver to make sterling silver, increasing its strength for use in dishes, silverware, and other practical items. Quite often, precious metals were alloyed with less valuable substances as a means to deceive buyers. Around 250 BC, Archimedes was commissioned by the king to find a way to check the purity of the gold in a crown, leading to the famous bath-house shouting of "Eureka!" upon the discovery of Archimedes' principle.
Who shouted "Eureka!" while checking the purity of a crown?
Archimedes

At the beginning of the Caliphate or Islamic Empire, the reliance on courts initially confined sponsorship and scholarly activities to major centres. Within several centuries, the development of Muslim educational institutions such as the madrasah and masjid eventually introduced such activities to provincial towns and dispersed them across the Islamic legal schools and Sufi orders. In addition to religious subjects, they also taught the "rational sciences," as varied as mathematics, astronomy, astrology, geography, alchemy, philosophy, magic, and occultism, depending on the curriculum of the specific institution in question. The madaris, however, were not centres of advanced scientific study; scientific advances in Islam were usually carried out by scholars working under the patronage of royal courts. During this time,[when?] the Caliphate experienced a growth in literacy, having the highest literacy rate of the Middle Ages, comparable to classical Athens' literacy in antiquity but on a much larger scale. The emergence of the maktab and madrasa institutions played a fundamental role in the relatively high literacy rates of the medieval Islamic world.
Who traditionally paid for scholars to study natural sciences?
royal courts
