Cuno Hoffmeister
Cuno Hoffmeister (2 February 1892 – 2 January 1968) was a German astronomer, observer and discoverer of variable stars, comets and minor planets, and founder of Sonneberg Observatory. Born in Sonneberg in 1892 to Carl and Marie Hoffmeister, Cuno Hoffmeister obtained his first telescope in 1905 and became an avid amateur astronomer. After his father lost most of his money in 1914, Hoffmeister had to leave school in 1916 to start an apprenticeship in his father's company. During this time he continued to study spherical mathematics and trigonometry. In April 1915 he had the opportunity to substitute as the assistant of Ernst Hartwig at ''Remeis Observatory'' in Bamberg while the current holder of the position was drafted, mainly working on observations of meteors and variable stars. He held this position until the end of the war and then moved back to Sonneberg, where he made his Abitur in 1920. After studying at the University of Jena, while at the same time continuing to work i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonneberg
Sonneberg in Thuringia, Germany, is the seat of the Sonneberg district. It is in the Franconian south of Thuringia, neighboring its Upper Franconian twin town Neustadt bei Coburg. Sonneberg became known as the "world toy city", and is home to the and the Sonneberg observatory, founded in 1925. The Thuringian Slate Mountains border the city, with the Franconian Forest to the east. History "The Sonneberg Castle was also called Sonneberg Castle or the Haus zu Sonneberg in old documents. In 480 Süne or Süno, Duke of Franconia, built this castle because of the Thuringian incursions ..." so it says on page 64 in the topography of the Duke of Saxe-Meiningen's share in the Duchy of Coburg from the year 1781. This not uncritical representation is based on the history of the Franks by Abbot Johannes Trithemius from 1514. The name Sonneberg was first mentioned in documents in 1207. It goes back to the noble family of the Lords of Sonneberg, which is documented in the 12th and 13th c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2183 Neufang
Year 183 (Roman numerals, CLXXXIII) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Victorinus (or, less frequently, year 936 ''Ab urbe condita''). The denomination 183 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Springer Publishing
Springer Publishing Company is an American publishing company of academic journals and books, focusing on the fields of nursing, gerontology, psychology, social work, counseling, public health, and rehabilitation (neuropsychology). It was established in 1951 by Bernhard Springer, a great-grandson of Julius Springer, and is based in Midtown Manhattan, New York City. History Springer Publishing Company was founded in 1950 by Bernhard Springer, the Berlin-born great-grandson of Julius Springer, who founded Springer-Verlag (now Springer Science+Business Media). Springer Publishing's first landmark publications included ''Livestock Health Encyclopedia'' by R. Seiden and the 1952 ''Handbook of Cardiology for Nurses''. The company's books soon branched into other fields, including medicine and psychology. Nursing publications grew rapidly in number, as Modell's ''Drugs in Current Use'', a small annual paperback, sold over 150,000 copies over several editions. Solomon Garb's ''Labor ...

Minor Planet Circulars
The Minor Planet Center (MPC) is the official body for observing and reporting on minor planets under the auspices of the International Astronomical Union (IAU). Founded in 1947, it operates at the Smithsonian Astrophysical Observatory. Function The Minor Planet Center is the official worldwide organization in charge of collecting observational data for minor planets (such as asteroids), calculating their orbits and publishing this information via the '' Minor Planet Circulars''. Under the auspices of the International Astronomical Union (IAU), it operates at the Smithsonian Astrophysical Observatory, which is part of the Center for Astrophysics along with the Harvard College Observatory. The MPC runs a number of free online services for observers to assist them in observing minor planets and comets. The complete catalogue of minor planet orbits (sometimes referred to as the "Minor Planet Catalogue") may also be freely downloaded. In addition to astrometric data, the MPC collect ...

1726 Hoffmeister
1726 Hoffmeister, provisional designation , is a carbonaceous asteroid and namesake of the Hoffmeister family from the central region of the asteroid belt, approximately 23 kilometers in diameter. It was discovered on 24 July 1933, by German astronomer Karl Reinmuth at Heidelberg Observatory in southwest Germany, and named after astronomer Cuno Hoffmeister. Orbit and classification ''Hoffmeister'' is the namesake and lowest-numbered member of the very compact Hoffmeister family (), which, based upon its low albedo, was most likely formed from the breakup of a 50–100 kilometer-sized, carbon-rich parent body within the past several hundred million years. It orbits the Sun in the central main-belt at a distance of 2.7–2.9 AU once every 4 years and 8 months (1,700 days; semi-major axis of 2.79 AU). Its orbit has an eccentricity of 0.04 and an inclination of 3 ° with respect to the ecliptic. It was first identified as at the Yerkes Observatory in 1924, extend ...

Hoffmeister (crater)
Hoffmeister is a lunar impact crater that is located on the Moon's far side, to the northwest of the huge walled plain Mendeleev. Some distance to the north of Hoffmeister lies the crater Siedentopf, and to the west-northwest is Gavrilov. This is a somewhat eroded crater with Hoffmeister N attached to the southern rim. A small crater with a high albedo Albedo (; ) is the measure of the diffuse reflection of sunlight, solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black body that absorbs all incident radiation, to 1, corresponding to a body ... lies along the common rim between Hoffmeister and this satellite. A small crater also lies along the northwestern rim of Hoffmeister. The interior floor of Hoffmeister is relatively featureless. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Hoffmeister. See also * 172 ...

Hyperbolic Comet
This is a list of parabolic and hyperbolic comets in the Solar System. Many of these comets may come from the Oort cloud, or perhaps even have interstellar origin. The Oort Cloud is not gravitationally attracted enough to the Sun to form into a fairly thin disk, like the inner Solar System. Thus, comets originating from the Oort Cloud can come from roughly any orientation (inclination to the ecliptic), and many even have a retrograde orbit. By definition, a hyperbolic orbit means that the comet will only travel through the Solar System once, with the Sun acting as a gravitational slingshot, sending the comet hurtling out of the Solar System entirely unless its eccentricity is otherwise changed. Comets orbiting in this way still originate from the Solar System, however. Typically comets in the Oort Cloud are thought to have roughly circular orbits around the Sun, but their orbital velocity is so slow that they may easily be perturbed by passing stars and the galactic tide.

Photographic Plate
Photographic plates preceded photographic film as a capture medium in photography, and were still used in some communities up until the late 20th century. The light-sensitive emulsion of silver salts was coated on a glass plate, typically thinner than common window glass. History Glass plates were far superior to film for research-quality imaging because they were stable and less likely to bend or distort, especially in large-format frames for wide-field imaging. Early plates used the wet collodion process. The wet plate process was replaced late in the 19th century by gelatin dry plates. A view camera nicknamed "The Mammoth" weighing was built by George R. Lawrence in 1899, specifically to photograph "The Alton Limited" train owned by the Chicago & Alton Railway. It took photographs on glass plates measuring × . Glass plate photographic material largely faded from the consumer market in the early years of the 20th century, as more convenient and less fragile fil ...
