Hopfner's Arc Measurement
Friedrich Hopfner (28 October 1881 – 5 September 1949) was an Austrian geodesist, geophysicist and planetary scientist. As an officer of the Austro-Hungarian Empire he began his scientific work at the Bureau of Meteorology. In 1921 he became Chief Astronomer at the new Geodetic Survey of Austria (Federal Office for Metrology and Survey or ''Bundesamt für Eich- und Vermessungswesen''). From 1936 to 1942 and from 1945 to 1949 he was a professor at the Vienna University of Technology (TU Wien) and over the 1948-9 term he was the university's rector. Life He was born on 28 October 1881 in Trautenau, northern Bohemia (now Trutnov, Czech Republic). He studied mathematics, physics, geophysics and astronomy at the University of Prague and the University of Munich between 1899 and 1904. In 1905 at the Charles University in Prague he delivered his dissertation on "The average and relative distribution of temperature on the Earth's surface." His first job was as an assistant at t ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, moons, comets and galaxies – in either observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, solar astronomy, the origin or evolution of stars, or the formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational and theoretical. Observational astronomers make direct observations of celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate models of things that cannot be observed. Because it takes millions to billions of years for a system of stars or a galaxy to complete a life cycle, astronomers must observe snapsh ...

Isonzo Army
The Austro-Hungarian Fifth Army was an Austro-Hungarian field army that fought during World War I. Actions The Fifth Army was formed in 1914 as part of Austro-Hungarian mobilization following its declaration of war on Serbia and Russia. The Fifth Army was put under the command of Gen. Liborius Ritter von Frank. Between August and December 1914, it fought in the Serbian Campaign and suffered such enormous casualties that it was disbanded on 27 December 1914. It participated in the : * Battle of Cer (August 1914), * Battle of Drina (September - October 1914) * Battle of Kolubara (November - December 1914). The Fifth Army was reestablished in May 1915 on the Italian Front, where it remained active until the end of the War. On 24 May 1917, it was renamed the Isonzo Army. On 23 August 1917, the Isonzo Army was upgraded to Army Group Boroević (Heeresgruppe "Boroević") which was composed of 2 armies: * First Isonzo Army, under command of Wenzel von Wurm. * Second Isonzo Army, un ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was List of wars and anthropogenic disasters by death toll, one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific Ocean, Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in Genocides in history (World War I through World War II), genocides within the Ottoman Empire and in the Spanish flu, 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising French Third Republic, France, Russia, and British Empire, Britain) and the Triple A ...

Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics ...

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting poin ...

Bohemia
Bohemia ( ; cs, Čechy ; ; hsb, Čěska; szl, Czechy) is the westernmost and largest historical region of the Czech Republic. Bohemia can also refer to a wider area consisting of the historical Lands of the Bohemian Crown ruled by the Bohemian kings, including Moravia and Czech Silesia, in which case the smaller region is referred to as Bohemia proper as a means of distinction. Bohemia was a duchy of Great Moravia, later an independent principality, a kingdom in the Holy Roman Empire, and subsequently a part of the Habsburg monarchy and the Austrian Empire. After World War I and the establishment of an independent Czechoslovak state, the whole of Bohemia became a part of Czechoslovakia, defying claims of the German-speaking inhabitants that regions with German-speaking majority should be included in the Republic of German-Austria. Between 1938 and 1945, these border regions were joined to Nazi Germany as the Sudetenland. The remainder of Czech territory became ...
