Collmberg
Collmberg ( Sorbian ''chołm'' - "Hill, mound“), regionally and colloquially called ''Collm'', is the highest elevation in the Nordsachsen district and of the Northwest Saxon Basin, situated 6 km west of Oschatz near the small village of Collm. Until the 19th Century it was also called ''Spielberg'' and has also been known as ''Oschatzer Collm''. Its height is 312.8 metres above sea level ( NHN), although map data vary between 312 m and 318 m depending on the source. Collmberg is a landmark in Wermsdorf Forest. Geology Collmberg consists chiefly of quartzitic Greywacke originating from the Ordovician more than 500 million years ago, also of quartzite and conglomerates. The hill was shaped in the Pleistocene epoch. Collmberg is the site of the oldest known exposed rocks in Northern Saxony. Its Greywacke can be traced towards East-northeast across the neighbouring hills until Weinberg hill near Borna and Käferberg hill near Zaußwitz. About 1 km east of ...

Grade Measurement
Arc measurement, sometimes degree measurement (german: Gradmessung), is the astrogeodetic technique of determining of the radius of Earth – more specifically, the local Earth radius of curvature of the figure of the Earth – by relating the latitude difference (sometimes also the longitude difference) and the geographic distance ( arc length) surveyed between two locations on Earth's surface. The most common variant involves only astronomical latitudes and the meridian arc length and is called ''meridian arc measurement''; other variants may involve only astronomical longitude ('' parallel arc measurement'') or both geographic coordinates (''oblique arc measurement''). Arc measurement campaigns in Europe were the precursors to the International Association of Geodesy (IAG). History The first known arc measurement was performed by Eratosthenes (240 BC) between Alexandria and Syene in what is now Egypt, determining the radius of the Earth with remarkable correctness.

Observation Tower
An observation tower is a structure used to view events from a long distance and to create a full 360 degree range of vision to conduct long distance observations. Observation towers are usually at least tall and are made from stone, iron, and wood. Many modern towers are also used as TV towers, restaurants, or churches. The towers first appeared in the ancient world, as long ago as the Babylonian Empire. Observation towers that are used as guard posts or observation posts over an extended period to overlook an area are commonly called watchtowers instead. Construction and usage Observation towers are an easily visible sight on the countryside, as they must rise over trees and other obstacles to ensure clear vision. Older control rooms have often been likened to medieval chambers. The heavy use of stone, iron, and wood in their construction helps to create this illusion. Modern towers frequently have observation decks or terraces with restaurants or on the roof of mountain st ...

Seismograph
A seismometer is an instrument that responds to ground noises and shaking such as caused by earthquakes, volcanic eruptions, and explosions. They are usually combined with a timing device and a recording device to form a seismograph. The output of such a device—formerly recorded on paper (see picture) or film, now recorded and processed digitally—is a seismogram. Such data is used to locate and characterize earthquakes, and to study the Earth's internal structure. Basic principles A simple seismometer, sensitive to up-down motions of the Earth, is like a weight hanging from a spring, both suspended from a frame that moves along with any motion detected. The relative motion between the weight (called the mass) and the frame provides a measurement of the vertical ground motion. A rotating drum is attached to the frame and a pen is attached to the weight, thus recording any ground motion in a seismogram. Any movement from the ground moves the frame. The mass tends not to m ...

Leipzig University
Leipzig University (german: Universität Leipzig), in Leipzig in Saxony, Germany, is one of the world's oldest universities and the second-oldest university (by consecutive years of existence) in Germany.

Geophysics
Geophysics () is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. The term ''geophysics'' sometimes refers only to solid earth applications: Earth's shape; its gravitational and magnetic fields; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation. However, modern geophysics organizations and pure scientists use a broader definition that includes the water cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial physics; and analogous problems associated with the Moon and other planets.

Thirty Years' War
The Thirty Years' War was one of the longest and most destructive conflicts in European history, lasting from 1618 to 1648. Fought primarily in Central Europe, an estimated 4.5 to 8 million soldiers and civilians died as a result of battle, famine, and disease, while some areas of what is now modern Germany experienced population declines of over 50%. Related conflicts include the Eighty Years' War, the War of the Mantuan Succession, the Franco-Spanish War, and the Portuguese Restoration War. Until the 20th century, historians generally viewed it as a continuation of the religious struggle initiated by the 16th-century Reformation within the Holy Roman Empire. The 1555 Peace of Augsburg attempted to resolve this by dividing the Empire into Lutheran and Catholic states, but over the next 50 years the expansion of Protestantism beyond these boundaries destabilised the settlement. While most modern commentators accept differences over religion and Imperial authority were ...

John George I, Elector Of Saxony
John George I (5 March 1585 – 8 October 1656) was Elector of Saxony from 1611 to 1656. He led Saxony through the Thirty Years' War, which dominated his 45 year reign. Biography Born in Dresden, John George was the second son of the Elector Christian I and Sophie of Brandenburg. He belonged to the Albertine line of the House of Wettin. John George succeeded to the electorate on 23 June 1611 on the death of his elder brother, Christian II. The geographical position of the Electorate of Saxony rather than her high standing among the German Protestants gave her ruler much importance during the Thirty Years' War. At the beginning of his reign, however, the new elector took up a somewhat detached position. His personal allegiance to Lutheranism was sound, but he liked neither the growing strength of Brandenburg nor the increasing prestige of the Palatinate; the adherence of the other branches of the Saxon ruling house to Protestantism seemed to him to suggest that the head of the ...
