Ernst Wilhelm Von Brücke
Ernst Wilhelm von Brücke (; 6 July 1819 – 7 January 1892) was a German physician and physiologist. He worked on the nature of cells, physiology of language, the effect of electricity on muscles, and studies of albumin. He also made significant contributions in the fields of physics, plant physiology, microscopic anatomy, and experimental physiology. He was an influential professor of Sigmund Freud. Biography He was born Ernst Wilhelm Brücke in Berlin. He graduated in medicine at the University of Berlin in 1842, and during the following year, he became a research assistant to Johannes Peter Müller. In 1845, he founded the Physikalische Gesellschaft (Physical Society) in Berlin, together with Emil Du Bois-Reymond, Hermann von Helmholtz and others, in the house of physicist Heinrich Gustav Magnus. Later on, this became known as the Deutsche Physikalische Gesellschaft (German Society of Physics). In 1846, Brücke was elected teacher of anatomy in the Akademie der Bildenden ...

Province Of Brandenburg
The Province of Brandenburg () was a province of Prussia from 1815 to 1947. Brandenburg was established in 1815 from the Kingdom of Prussia's core territory, comprised the bulk of the historic Margraviate of Brandenburg (excluding Altmark) and the Lower Lusatia region, and became part of the German Empire in 1871. From 1918, Brandenburg was a province of the Free State of Prussia until Prussia was dissolved in 1945 after World War II, and replaced with reduced territory as the State of Brandenburg in East Germany, which was later dissolved in 1952. Following the reunification of Germany in 1990, Brandenburg was re-established as a federal state of Germany, becoming one of the new states. Brandenburg's provincial capital alternated between Potsdam, Berlin, and Charlottenburg during its existence. Geography The province comprised large parts of the North German Plain, stretching from the Elbe river in the west to beyond the Oder in the east, where the Neumark region bordered ...

Hermann Von Helmholtz
Hermann Ludwig Ferdinand von Helmholtz (; ; 31 August 1821 – 8 September 1894; "von" since 1883) 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, was named in his honour. 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, colour 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 and on the electrical double layer, work in electrodynamics, chemical thermodynamics, and on a mechanical foundation of thermodynamics. Although credit is shared with Julius von Mayer, James Joule, and Daniel Bernoulli—among others—for the energy conservation principles that e ...

Tapetum Lucidum
The ; ; : tapeta lucida) is a layer of tissue in the eye of many vertebrates and some other animals. Lying immediately behind the retina, it is a retroreflector. It Reflection (physics), reflects visible light back through the retina, increasing the light available to the Photoreceptor cell, photoreceptors (although slightly blurring the image). The tapetum lucidum contributes to the superior night vision of some animals. Many of these animals are nocturnality, nocturnal, especially carnivores, while others are Deep-sea community, deep-sea animals. Similar adaptations occur in some species of spiders. Haplorhini, Haplorhine primates, including humans, are Diurnality, diurnal and lack a tapetum lucidum. Function and mechanism The presence of a tapetum lucidum enables animals to see in dimmer light than would otherwise be possible. The tapetum lucidum, which is iridescent, reflects light roughly on the Interference (wave propagation), interference principles of thin-film opti ...

Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of optical instruments, instruments that use or Photodetector, detect it. Optics usually describes the behaviour of visible light, visible, ultraviolet, and infrared light. Light is a type of electromagnetic radiation, and other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the Classical electromagnetism, classical electromagnetic description of light, however complete electromagnetic descriptions of light are often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of Ray (optics), rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychodynamics
Psychodynamics, also known as psychodynamic psychology, in its broadest sense, is an approach to psychology that emphasizes systematic study of the psychological forces underlying human behavior, feelings, and emotions and how they might relate to early experience. It is especially interested in the dynamic relations between conscious motivation and unconscious motivation. The term psychodynamics is sometimes used to refer specifically to the psychoanalytical approach developed by Sigmund Freud (1856–1939) and his followers. Freud was inspired by the theory of thermodynamics and used the term psychodynamics to describe the processes of the mind as flows of psychological energy ( libido or psi) in an organically complex brain. However, modern usage differentiates psychoanalytic practice as referring specifically to the earliest forms of psychotherapy, practiced by Freud and his immediate followers, and psychodynamic practice as practice that is informed by psychoanalytic theo ...

Joseph Paneth
Joseph Paneth (6 October 1857 – 4 January 1890) was an physiologist born in Vienna. Paneth is remembered for his description of "Paneth cells", which are cells that provide host defense against microbes in the mucosa of the small intestine. He studied at the Universities of Heidelberg and Vienna, where he worked with physiologist Ernst Wilhelm von Brücke (1819–1892). After a short stay at the University of Breslau, he returned to Vienna, where in 1886 he became a lecturer at the university. In 1883 and 1884 he worked at the zoological station at Villefranche, near Nice. He was a good friend of psychologist Sigmund Freud, who made a posthumous reference of Paneth in ''The Interpretation of Dreams''. Paneth is also remembered for his correspondence with |

Karl Friedrich Burdach (12 June 1776 – 16 July 1847) was a German physiologist. He was the first to use the word "biology" and was a pioneer of neuroanatomy. Life Burdach came from a family of physicians in Leipzig.
