J. G. Westphal
Justus Georg Westphal (18 March 1824 – 9 November 1859) was a German astronomer and mathematician. Westphal is not to be confused with Johann Heinrich Westphal (1794 – 1831). Within the NASA Astrophysics Data System (ADS) he also appears to be confused with a third Westphal, "Alfred Friedrich Julius Westphal" ("Dr. A. Westphal"), a geophysicist who lived from 1 August 1850 to 1924, and who first published in 1881. J. G. Westphal is only mentioned a few times in the ADS, between 1853 and 1859. Life Westphal was born on 18 March 1824 in Colborn near Lüchow.Poggendorf, J. C.

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, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, 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 astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Carl Friedrich Gauss
Johann Carl Friedrich Gauss (; german: Gauß ; la, Carolus Fridericus Gauss; 30 April 177723 February 1855) was a German mathematician and physicist who made significant contributions to many fields in mathematics and science. Sometimes referred to as the ''Princeps mathematicorum'' () and "the greatest mathematician since antiquity", Gauss had an exceptional influence in many fields of mathematics and science, and he is ranked among history's most influential mathematicians. Also available at Retrieved 23 February 2014. Comprehensive biographical article. Biography Early years Johann Carl Friedrich Gauss was born on 30 April 1777 in Brunswick (Braunschweig), in the Duchy of Brunswick-Wolfenbüttel (now part of Lower Saxony, Germany), to poor, working-class parents.

Ernst Friedrich Wilhelm Klinkerfues
Ernst Friedrich Wilhelm Klinkerfues (29 March 1827 in Hofgeismar – 28 January 1884 in Göttingen) was a German astronomer and meteorologist. He discovered six comets and published weather reports of varying accuracy based on his meteorological measurements. Early life Klinkerfues was born in Hofgeismar, the son of army doctor Johann Reinhard Klinkerfues and his wife Sabine (née Dedolph). After the early death of his parents, he was brought up by relatives, and after attending high school qualified as a surveyor in Kassel. In this capacity he subsequently worked on the new Frankfurt - Kassel railway. From 1847 to 1851 Klinkerfues studied mathematics and astronomy at the University of Marburg. He then became an assistant to Carl Friedrich Gauss at Göttingen Observatory, where he completed his Ph.D. with a thesis on orbit calculations of double stars. After Gauss' death in 1855, the mathematician W. E. Weber replaced him as director, but Klinkerfues was to be temporari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

19th-century German Astronomers
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discoverers Of Comets
Discovery is the act of detecting something new, or something previously unrecognized as meaningful. With reference to sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and providing new reasoning to explain the knowledge gathered through such observations with previously acquired knowledge from abstract thought and everyday experiences. A discovery may sometimes be based on earlier discoveries, collaborations, or ideas. Some discoveries represent a radical breakthrough in knowledge or technology. New discoveries are acquired through various senses and are usually assimilated, merging with pre-existing knowledge and actions. Questioning is a major form of human thought and interpersonal communication, and plays a key role in discovery. Discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. A discovery may sometimes be based on earlier discoveries, collabo ...
