Karl Wilhelm Valentiner
Karl Wilhelm Valentiner (22 February 1845 in Eckernförde – 1 April 1931) was a German astronomer. Life In 1874, Wilhelm Valentiner led a successful German expedition to Zhifu (China) to observe a solar eclipse. 1875, He took over the directorship of the Mannheim Observatory in 1875. Since the observing conditions in the Mannheim city centre were deteriorating, Grand Duke Frederick I of Baden approved Valentiner's request to relocate the observatory in Karlsruhe in 1880. The telescope, however, was located in a makeshift hut in Karlsruhe Nymphenburg Park. Much to the annoyance of Valentiner, now appointed Professor of the University of Karlsruhe, no new observatory was built. He decided to apply for a position at Königstuhl near Heidelberg. After the establishment of the "Grand Duchy Mountain Observatory" (today's Heidelberg-Königstuhl State Observatory) in the year 1898 Valentiner was placed over the Department of Astrometry, which stood in competition with the Astrophysi ...

Eckernförde
Eckernförde (; , sometimes also ; , sometimes also ) is a city located in the of Rendsburg-Eckernförde, Schleswig-Holstein, northern Germany. Situated on the coast of the Baltic Sea, approximately 30 km north-west of Kiel, it has a population of about 23,000. Eckernförde is a popular tourist destination. Name The name of Eckernförde is of mixed origin, but derived from the name of a Danish castle formerly located near the current town, which is also reflected in the name of the town district of ''Borby.'' This fortification is listed in the 13th-century Liber Census Daniæ (Danish Census Book) as ''Ykærnæburgh.''Politikens Nudansk Ordbog, 1994 edition, entry "Eckernförde" In 1441, the town used an official seal listing its name as ''Eherneborgh''.Poul Bredo Grandjean (1953), ''Slesvigske Købstæders og Herreders Segl indtil 1660'', J.H. Schultz Forlag, p. 13-14. The first syllable corresponds to the modern Danish word "egern" meaning ''squirrel'', while "-förde" i ...

Telescope
A telescope is a device used to observe distant objects by their emission, Absorption (electromagnetic radiation), absorption, or Reflection (physics), reflection of electromagnetic radiation. Originally, it was an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects – an optical telescope. Nowadays, the word "telescope" is defined as a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors. The first known practical telescopes were refracting telescopes with glass lenses and were invented in the Netherlands at the beginning of the 17th century. They were used for both terrestrial applications and astronomy. The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types of telescopes were invented, including radio telescopes in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Eckernförde
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1845 Births
Events January–March * January 1 – The Philippines began reckoning Asian dates by hopping the International Date Line through skipping Tuesday, December 31, 1844. That time zone shift was a reform made by Governor–General Narciso Claveria on August 16, 1844, in order to align the local calendars in the country with the rest of Asia as trade interests with Imperial China, Dutch East Indies and neighboring countries increased, after Mexico became independent in 1821. The reform also applied to Caroline Islands, Guam, Marianas Islands, Marshall Islands, and Palau as part of the Captaincy General of the Philippines. * January 10 – Elizabeth Barrett receives a love letter from the younger poet Robert Browning; on May 20, they meet for the first time in London.

Max Wolf
Maximilian Franz Joseph Cornelius Wolf (21 June 1863 – 3 October 1932) was a German astronomer and a pioneer in the field of astrophotography. He was the chairman of astronomy at the University of Heidelberg and director of the Heidelberg-Königstuhl State Observatory from 1902 until his death in 1932. Early life Max Wolf was born in Heidelberg, Germany on 21 June 1863, the son of medical doctor Franz Wolf. His father encouraged an interest in science and built an observatory for his son in the garden of the family home. It is from here that Wolf was credited with his first astronomical discovery, comet 14P/Wolf, in 1884. Life at the university Wolf attended his local university and, in 1888, at the age of 25, was awarded a Doctor of Philosophy, Ph.D. by the University of Heidelberg. He spent one year of post-graduate study in Stockholm, the only significant time he would spend outside of Heidelberg in his life. He returned to the University of Heidelberg and accepted ...

Astrophysics
Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. As one of the founders of the discipline, James Keeler, said, astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space—''what'' they are, rather than ''where'' they are", which is studied in celestial mechanics. Among the subjects studied are the Sun ( solar physics), other stars, galaxies, extrasolar planets, the interstellar medium, and the cosmic microwave background. Emissions from these objects are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, ''astrophysicists'' apply concepts and methods from many disciplines of physics, including classical mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum ...

Astrometry
Astrometry is a branch of astronomy that involves precise measurements of the positions and movements of stars and other Astronomical object, celestial bodies. It provides the kinematics and physical origin of the Solar System and this galaxy, the Milky Way. History The history of astrometry is linked to the history of star catalogues, which gave astronomers reference points for objects in the sky so they could track their movements. This can be dated back to the ancient Greek astronomer Hipparchus, who around 190 BC used the catalogue of his predecessors Timocharis and Aristillus to discover Earth's precession. In doing so, he also developed the brightness scale still in use today. Hipparchus compiled a catalogue with at least 850 stars and their positions. Hipparchus's successor, Ptolemy, included a catalogue of 1,022 stars in his work the ''Almagest'', giving their location, coordinates, and brightness. In the 10th century, the Iranian astronomer Abd al-Rahman al-Sufi carried ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Königstuhl (Odenwald)
The Königstuhl (), is a high hill in the Odenwald Mountains and in the city of Heidelberg, in the German state of Baden-Württemberg. The Königstuhl summit allows visitors views of the city of Heidelberg and the Neckar river. On days with good conditions the view extends to the Pfaelzerwald (Palatinate Forest), which is roughly 40–50 km away. The hill is linked to Altstadt, by the Heidelberger Bergbahn, a two section historic funicular railway that stops at Heidelberg Castle, located on the lower slopes of the Königstuhl, the Molkenkur restaurant/hotel, and the ultimate stop at the mountain top which host a restaurant, an entertainment park for kids and various walking paths. The Max Planck Institute for Astronomy is located near the summit of the Königstuhl, as is the historic Landessternwarte Heidelberg-Königstuhl astronomical observatory, established in 1898.

University Of Karlsruhe
The Karlsruhe Institute of Technology (KIT; ) is both a German public university, public research university in Karlsruhe, Baden-Württemberg, and a research center of the Helmholtz Association. KIT was created in 2009 when the University of Karlsruhe (), founded in 1825 as a public research university and also known as the "Fridericiana", merged with the Karlsruhe Research Center (), which had originally been established in 1956 as a national nuclear research center (, or KfK). KIT is thus the first and only institution in Germany to overcome the division of the German scientific and research landscape into academic and non-academic institutions in the form of a merger of two different types of institutions. KIT is a member of the TU9, an incorporated society of the largest and most notable German institutes of technology. As part of the German Universities Excellence Initiative KIT was one of three universities which were awarded excellence status in 2006. In the following "G ...
