Budapest
Budapest (, ; ) is the capital and most populous city of Hungary. It is the ninth-largest city in the European Union by population within city limits and the second-largest city on the Danube river; the city has an estimated population of 1,752,286 over a land area of about . Budapest, which is both a city and county, forms the centre of the Budapest metropolitan area, which has an area of and a population of 3,303,786; it is a primate city, constituting 33% of the population of Hungary. The history of Budapest began when an early Celtic settlement transformed into the Roman town of Aquincum, the capital of Lower Pannonia. The Hungarians arrived in the territory in the late 9th century, but the area was pillaged by the Mongols in 1241–42. Re-established Buda became one of the centres of Renaissance humanist culture by the 15th century. The Battle of Mohács, in 1526, was followed by nearly 150 years of Ottoman rule. After the reconquest of Buda in 1686, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the H ...

Rudolf Kirchschläger
Rudolf Kirchschläger, GColIH (; 20 March 1915 – 30 March 2000) was an Austrian diplomat, politician and judge. From 1974 to 1986, he served as President of Austria. Early life and education Born in Niederkappel, Upper Austria, Kirschläger was orphaned at the age of 11. He graduated from high school in Horn in 1935 with distinction and started to study law at the University of Vienna. However, after the Anschluss of Austria in 1938, he had to give up his studies. Without joining the NSDAP, which he refused to do, his scholarship was revoked and Kirchschläger could not finance his studies any longer. Kirchschläger worked as a bank clerk in 1938 until he was drafted to service in the infantry of the Wehrmacht in the summer of 1939. Kirchschläger fought as a soldier from the very beginning of the war, first during the invasion of Poland, later on the Western Front, and after 1941 against Russia on the Eastern Front. In late 1940, in order to get out of the military, he us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
President Of Austria
The president of Austria (german: Bundespräsident der Republik Österreich) is the head of state of the Republic of Austria. Though theoretically entrusted with great power by the Constitution, in practice the president is largely a ceremonial and symbolic figurehead. The office of the president was established in 1920 following the collapse of the Austro-Hungarian Empire and the Habsburg monarchy in 1918. As head of state, the president succeeded the chair of the Constituent Assembly, the post-monarchic provisional legislature. Originally intended to be chosen directly by the Austrian people through universal suffrage every six years, the president was instead appointed by the legislative Federal Assembly until 1951, when Theodor Körner became the first popularly-elected president. Since the institution of the popular vote, only nominees of the Social Democratic Party and the People's Party had been elected to the presidency, with the exception of the Green-endorsed incumb ...

Rubber Elasticity
Rubber elasticity refers to a property of crosslinked rubber: it can be stretched by up to a factor of 10 from its original length and, when released, returns very nearly to its original length. This can be repeated many times with no apparent degradation to the rubber. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and technological importance. Elastomers have played a key role in the development of new technologies in the 20th century and make a substantial contribution to the global economy. Rubber elasticity is produced by several complex molecular processes and its explanation requires a knowledge of advanced mathematics, chemistry and statistical physics, particularly the concept of entropy. Entropy may be thought of as a measure of the thermal energy that is stored in a molecule. Common rubbers, such as polybutadiene and polyisoprene (also called natural rubber), are produced by a process called pol ...

Entropic
Entropy is a scientific concept, as well as a measurable physical property, that is most commonly associated with a state of disorder, randomness, or uncertainty. The term and the concept are used in diverse fields, from classical thermodynamics, where it was first recognized, to the microscopic description of nature in statistical physics, and to the principles of information theory. It has found far-ranging applications in chemistry and physics, in biological systems and their relation to life, in cosmology, economics, sociology, weather science, climate change, and information systems including the transmission of information in telecommunication. The thermodynamic concept was referred to by Scottish scientist and engineer William Rankine in 1850 with the names ''thermodynamic function'' and ''heat-potential''. In 1865, German physicist Rudolf Clausius, one of the leading founders of the field of thermodynamics, defined it as the quotient of an infinitesimal amount of heat ...

Brownian Motion
Brownian motion, or pedesis (from grc, πήδησις "leaping"), is the random motion of particles suspended in a medium (a liquid or a gas). This pattern of motion typically consists of random fluctuations in a particle's position inside a fluid sub-domain, followed by a relocation to another sub-domain. Each relocation is followed by more fluctuations within the new closed volume. This pattern describes a fluid at thermal equilibrium, defined by a given temperature. Within such a fluid, there exists no preferential direction of flow (as in transport phenomena). More specifically, the fluid's overall linear and angular momenta remain null over time. The kinetic energies of the molecular Brownian motions, together with those of molecular rotations and vibrations, sum up to the caloric component of a fluid's internal energy (the equipartition theorem). This motion is named after the botanist Robert Brown, who first described the phenomenon in 1827, while looking throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
