Joseph Von Fraunhofer
Joseph Ritter von Fraunhofer (; ; 6 March 1787 – 7 June 1826) was a German physicist and optical lens manufacturer. He made optical glass, an achromatic telescope, and objective lenses. He also invented the spectroscope and developed diffraction grating. In 1814, he discovered and studied the dark absorption lines in the spectrum of the sun now known as Fraunhofer lines. The German research organization Fraunhofer Society, which is Europe's biggest Society for the advancement of applied research, is named after him. Biography Joseph Fraunhofer was the 11th child, born into a Roman Catholic family in Straubing, in the Electorate of Bavaria, to Franz Xaver Fraunhofer and Maria Anna Fröhlich. He was orphaned at the age of 11 and started working as an apprentice to a harsh glassmaker named Philipp Anton Weichelsberger. In 1801, the workshop in which he was working collapsed, and he was buried in the rubble. The rescue operation was led by Prince-Elector Maximilian Joseph. The ...

Straubing
Straubing () is an independent city in Lower Bavaria, southern Germany. It is seat of the district of Straubing-Bogen. Annually in August the Gäubodenvolksfest, the second largest fair in Bavaria, is held. The city is located on the Danube forming the centre of the Gäuboden. History The area of Straubing has been continuously settled since the Neolithic. The conquest by the Romans in 16–14 BC had a dramatic impact on the whole region. Even today many traces of the 400-year Roman occupation can be found: for example, the famous 'Römerschatz' (Roman treasure) which was excavated in 1950 and which is shown in the Gäubodenmuseum. ''Sorviodurum'', as the Romans called it, was an important military support base. After the fall of the Roman Empire Straubing became a centre of settlement of the Bavarii, mostly around St. Peter's Church (built in the 9th century) between Allachbach and Danube. According to the customs of the Bavarii the settlement was named after their leader ''S ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Applied Research
Applied science is the use of the scientific method and knowledge obtained via conclusions from the method to attain practical goals. It includes a broad range of disciplines such as engineering and medicine. Applied science is often contrasted with basic science, which is focused on advancing scientific theories and laws that explain and predict events in the natural world. Applied science can also apply formal science, such as statistics and probability theory, as in epidemiology. Genetic epidemiology is an applied science applying both biological and statistical methods. Applied research Applied research is the practical application of science. It accesses and uses accumulated theories, knowledge, methods, and techniques, for a specific state-, business-, or client-driven purpose. Applied Research can be better understood in any area when contrasting it with, basic, or pure, research. Basic geography research strives to create new theories and methods that aid in the expl ...

University Of Erlangen
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

Honorary Doctorate
An honorary degree is an academic degree for which a university (or other degree-awarding institution) has waived all of the usual requirements. It is also known by the Latin phrases ''honoris causa'' ("for the sake of the honour") or ''ad honorem '' ("to the honour"). The degree is typically a doctorate or, less commonly, a master's degree, and may be awarded to someone who has no prior connection with the academic institution or no previous postsecondary education. An example of identifying a recipient of this award is as follows: Doctorate in Business Administration (''Hon. Causa''). The degree is often conferred as a way of honouring a distinguished visitor's contributions to a specific field or to society in general. It is sometimes recommended that such degrees be listed in one's curriculum vitae (CV) as an award, and not in the education section. With regard to the use of this honorific, the policies of institutions of higher education generally ask that recipients ...

Physics Today
''Physics Today'' is the membership magazine of the American Institute of Physics. First published in May 1948, it is issued on a monthly schedule, and is provided to the members of ten physics societies, including the American Physical Society. It is also available to non-members as a paid annual subscription. The magazine informs readers about important developments in overview articles written by experts, shorter review articles written internally by staff, and also discusses issues and events of importance to the science community in politics, education, and other fields. The magazine provides a historical resource of events associated with physics. For example it discussed debunking the physics of the Star Wars program of the 1980s, and the state of physics in China and the Soviet Union during the 1950s and 1970s. According to the ''Journal Citation Reports'', the journal has a 2017 impact factor The impact factor (IF) or journal impact factor (JIF) of an academic journa ...

Michael Faraday
Michael Faraday (; 22 September 1791 – 25 August 1867) was an English scientist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis. Although Faraday received little formal education, he was one of the most influential scientists in history. It was by his research on the magnetic field around a conductor carrying a direct current that Faraday established the concept of the electromagnetic field in physics. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena.. the 1911 Encyclopædia Britannica. He similarly discovered the principles of electromagnetic induction, diamagnetism, and the laws of electrolysis. His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts t ...

Pierre-Louis Guinand
Markree Observatory was an astronomical observatory in County Sligo, Ireland. The asteroid 9 Metis was discovered from this observatory in 1848 by Cooper's assistant Andrew Graham using a comet seeker telescope. (Signed 29 April 1848; the discovery was first announced on 27 April) The observatory was also home to the largest refractor of the early 1830s, which had a aperture Cauchoix of Paris lens; the largest in the world at that time. The observatory also housed a number of instruments and was operated to varying degrees throughout the 19th century. The observatory is noted for its discovery of the asteroid 9 Metis in 1848 as well as a 60,000 item star catalogue of the 1850s. In the later 1800s it was operated again after a brief hiatus, and gained note for its meteorological observations and research on double stars. History In 1830, Colonel Edward Joshua Cooper MP (1798–1863) eldest son of Edward Synge Cooper MP, and Ann, daughter of Henry Vansittart, Governor of Bengal, ...

Dispersion (optics)
In optics, and by analogy other branches of physics dealing with wave propagation, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency; sometimes the term chromatic dispersion is used for specificity to optics in particular. A medium having this common property may be termed a dispersive medium (plural ''dispersive media''). Although the term is used in the field of optics to describe light and other electromagnetic waves, dispersion in the same sense can apply to any sort of wave motion such as acoustic dispersion in the case of sound and seismic waves, and in gravity waves (ocean waves). Within optics, dispersion is a property of telecommunication signals along transmission lines (such as microwaves in coaxial cable) or the pulses of light in optical fiber. Physically, dispersion translates in a loss of kinetic energy through absorption. In optics, one important and familiar consequence of dispersion is the change in the angle of refra ...

Benediktbeuern Abbey
Benediktbeuern Abbey (Kloster Benediktbeuern) is an institute of the Salesians of Don Bosco, originally a monastery of the Benedictine Order, in Benediktbeuern in Bavaria, near the Kochelsee, 64 km south-south-west of Munich. It is the oldest and one of the most beautiful monasteries in Upper Bavaria. First Benedictine foundation The monastery, dedicated to Saints James, son of Zebedee, James and Benedict of Nursia, Benedict, was founded in around 739/740 as a Benedictine abbey by members of the Huosi, a Bavarian noble clan, who also provided the three brothers who served one after the other as the first three abbots, traditionally named as Lanfrid, Waldram (or Wulfram), and Eliland, for nearly a century. It is possible that Saint Boniface had an involvement in the foundation; he may have consecrated the church (to the holy Trinity), though this is not widely accepted. There was here a school of writing, whose work survives in the form of numerous codices of the 8th and 9th ce ...

Georg Von Reichenbach
Georg Friedrich von Reichenbach (24 August 1772 – 21 May 1826), German scientific instrument maker, was born at Durlach in Baden on 24 August 1772. Early life Reichenbach's father was a master mechanic, and a master cannon-borer, who moved to Mannheim when Reichenbach was two, and became manager of the cannon-boring works there. At 14 Georg was admitted to the Military School at Mannheim where he got to know the astronomer at the Mannheim Observatory. He received a knowledge of mathematical instruments and was inspired to try to construct similar instruments in his father's workshop. The Director of the Observatory sent a sextant made by Reichenbach to Count Rumford. When he was 19, Reichenbach received a grant of 500 gulden for a journey to London, and introductions to the engineers James Watt and Matthew Boulton. Reichenbach's first visit to England lasted from 1 June 1791 to January 1792, when he returned home for a short time before returning to England. He made drawings of ...
