Ludwig Holborn
Ludwig Friedrich Christian Holborn (29 September 1860 – 19 September 1926) was a German physicist known for his work in the measurement of high temperature using optical pyrometry. Holborn was born in Weende, Göttingen, the son of Louis and Louise née Oelsen. He studied at the Realschule and then went to the University of Göttingen where he studied natural sciences. He then taught mathematics and physics while also serving as an assistant to Ernst Christian Julius Schering at the Göttingen geomagnetic observatory (Gaußschen Erdmagnetischen Observatorium). He received a doctorate in 1887 for studies on the daily variation of magnetic declination. In 1890 he joined the Physikalisch-Technische Reichsanstalt, working there with Hermann von Helmholtz at Charlottenberg and designed a torsion magnetometer in 1903 in collaboration with F.W.G. Kohlrausch. In 1901 he designed what is sometimes called the Holborn-Kurlbaum pyrometer in collaboration with Ferdinand Kurlbaum. This optic ...

Göttingen
Göttingen (, , ; nds, Chöttingen) is a college town, university city in Lower Saxony, central Germany, the Capital (political), capital of Göttingen (district), the eponymous district. The River Leine runs through it. At the end of 2019, the population was 118,911. General information The origins of Göttingen lay in a village called ''Gutingi, ''first mentioned in a document in 953 AD. The city was founded northwest of this village, between 1150 and 1200 AD, and adopted its name. In Middle Ages, medieval times the city was a member of the Hanseatic League and hence a wealthy town. Today, Göttingen is famous for its old university (''Georgia Augusta'', or University of Göttingen, "Georg-August-Universität"), which was founded in 1734 (first classes in 1737) and became the most visited university of Europe. In 1837, seven professors protested against the absolute sovereignty of the House of Hanover, kings of Kingdom of Hanover, Hanover; they lost their positions, but be ...

University Of Göttingen
The University of Göttingen, officially the Georg August University of Göttingen, (german: Georg-August-Universität Göttingen, known informally as Georgia Augusta) is a public research university in the city of Göttingen, Germany. Founded in 1734 by George II, King of Great Britain and Elector of Hanover, and starting classes in 1737, the Georgia Augusta was conceived to promote the ideals of the Enlightenment. It is the oldest university in the state of Lower Saxony and the largest in student enrollment, which stands at around 31,600. Home to many noted figures, it represents one of Germany's historic and traditional institutions. According to an official exhibition held by the University of Göttingen in 2002, 44 Nobel Prize winners had been affiliated with the University of Göttingen as alumni, faculty members or researchers by that year alone. The University of Göttingen was previously supported by the German Universities Excellence Initiative, holds memberships ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Christian Julius Schering
Ernst Christian Julius Schering (13 July 1833 – 2 November 1897) was a German mathematician. Early life and career Born in 1833 near Bleckede at the Elbe as the son of a forester, he attended Realschule ("Johanneum") in Lüneburg from 1845 to 1850, where he already showed a certain talent for mathematics. With the intention to engage in architectural engineering, he attended the Polytechnicum in Hannover from 1850 to 1852. At the University of Göttingen Following a fondness of mathematics and physics, in 1852, at the age of 19, he moved on to study in Göttingen, attending classes by Gauß, Weber, Dirichlet, Stern and Riemann. In 1857, he received a doctoral degree for his award-winning manuscript "Zur mathematischen Theorie electrischer Ströme" ("On the mathematical theory of electric currents"). In 1858, he habilitated based on his work "Über die conforme Abbildung des Ellipsoids auf der Ebene" ("On the conformal mapping of the ellipsoid on the plane"). After turning ...

Hermann Von Helmholtz
Hermann Ludwig Ferdinand von Helmholtz (31 August 1821 – 8 September 1894) was a German physicist and physician who made significant contributions in several scientific fields, particularly hydrodynamic stability. The Helmholtz Association, the largest German association of research institutions, is named in his honor. In the fields of physiology and psychology, Helmholtz is known for his mathematics concerning the eye, theories of vision, ideas on the visual perception of space, color vision research, the sensation of tone, perceptions of sound, and empiricism in the physiology of perception. In physics, he is known for his theories on the conservation of energy, work in electrodynamics, chemical thermodynamics, and on a mechanical foundation of thermodynamics. As a philosopher, he is known for his philosophy of science, ideas on the relation between the laws of perception and the laws of nature, the science of aesthetics, and ideas on the civilizing power of science. ...

Friedrich Kohlrausch (physicist)
Friedrich Wilhelm Georg Kohlrausch (14 October 1840 – 17 January 1910) was a German physicist who investigated the conductive properties of electrolytes and contributed to knowledge of their behaviour. He also investigated elasticity, thermoelasticity, and thermal conduction as well as magnetic and electrical precision measurements. Nowadays, Friedrich Kohlrausch is classed as one of the most important experimental physicists. His early work helped to extend the absolute system of Carl Friedrich Gauss and Wilhelm Weber to include electrical and magnetic measuring units. Biography Education Son of Rudolf Kohlrausch, Friedrich Wilhelm Georg Kohlrausch was born on October 14, 1840, in Rinteln, Germany. After studying physics at Erlangen and Göttingen, Friedrich Kohlrausch completed his doctorate in Göttingen. Teaching After a two-year work as a lecturer in Frankfurt, Kohlrausch was appointed a professor of physics at the University of Göttingen (1866–70). During 1870 Koh ...

1860 Births
Year 186 ( CLXXXVI) was a common year starting on Saturday (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 Glabrio (or, less frequently, year 939 ''Ab urbe condita''). The denomination 186 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.
