Sigmund Exner
Sigmund Exner (also ''Sigmund Exner'', ''Siegmund Exner-Ewarten'', ''Siegmund Exner Ritter von Ewarten''; 5 April 1846 – 5 February 1926) was an Austrian physiologist born in Vienna. Academic career He studied in Vienna under Ernst Wilhelm von Brücke (1819–1892), and in Heidelberg with Hermann von Helmholtz (1821–1894). In 1870 he received his degree, subsequently working as an assistant in the physiological institute at the University of Vienna. In 1891 he succeeded Ernst von Brücke as professor of physiology and director of the physiological institute. During his career, he received honorary doctorates from the Universities of Leipzig and Athens. Physiological research Sigmund Exner is known for his work in comparative physiology, and his studies of perception psychology from a physiological standpoint. He conducted important research on localization of behavioral functionality in the brain, in particular studies on the functional architecture of the visual cortex ...

Ritter
Ritter (German for "knight") is a designation used as a title of nobility in German-speaking areas. Traditionally it denotes the second-lowest rank within the nobility, standing above "Edler" and below "Freiherr" (Baron). As with most titles and designations within the nobility in German-speaking areas, the rank was hereditary and generally was used with the nobiliary particle of von or zu before a family name. For its historical association with warfare and the landed gentry in the Middle Ages, the title of Ritter can be considered roughly equal to the titles of "Knight", but it is hereditary like the British title of "Baronet". The wife of a Ritter was called a "Frau" (in this sense "Lady") and not Ritterin. In heraldry, from the late 18th century a Ritter was often indicated by the use of a coronet with five points, although not everyone who was a Ritter and displayed arms made use of such a coronet. In the Austrian Empire and Austria-Hungary the title of "Ritter von" was ...

Beta Movement
The term Beta movement is used for the optical illusion of apparent motion in which the very short projection of one figure and a subsequent very short projection of a more or less similar figure in a different location are experienced as one figure that moves. The illusion of motion caused by animation and film is sometimes believed to rely on beta movement, as an alternative to the older explanation known as persistence of vision. However, there are notable differences between the short-range apparent motion that occurs in film (with little differences between successive images) and the long-range apparent motion originally described as beta movement (with bigger differences between positions of successive images). Examples of use The beta movement effect has been widely used in news ticker technology and is commonly seen in LED displays. History Observations of apparent motion through quick succession of images go back to the 19th century. In 1833, Joseph Plateau introd ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Franz-Serafin Exner
Franz Serafin Exner (24 March 1849 – 15 October 1926) was an Austrian physicist. Life Exner came from one of the most important university families of the Austrian-Hungarian empire. The same Exner family included , , Sigmund Exner, and . Exner was youngest of the five children who survived to adulthood of parents :de:Franz Serafin Exner, Franz Serafin Exner (1802-1853) and Charlotte Dusensy (1816–1859). His father Franz Serafin was, from 1831 to 1848, a professor of philosophy in Prague and from 1848 onwards a member of the Board of Education in Vienna, becoming an influential reformer of Austrian university education. Franz Exner began his university Physics studies at Vienna in 1867. He received a doctorate from the University of Vienna in 1871, after an academic year at University of Zurich, Zürich under August Kundt, also working alongside Wilhelm Conrad Röntgen, Kundt's student and, especially through the 1879s, regular research assistant/partner. The greatest ...

Philosopher
A philosopher is a person who practices or investigates philosophy. The term ''philosopher'' comes from the grc, φιλόσοφος, , translit=philosophos, meaning 'lover of wisdom'. The coining of the term has been attributed to the Greek thinker Pythagoras (6th century BCE).. In the Classics, classical sense, a philosopher was someone who lived according to a certain way of life, focusing upon resolving Meaning of life, existential questions about the human condition; it was not necessary that they discoursed upon Theory, theories or commented upon authors. Those who most arduously committed themselves to this lifestyle would have been considered ''philosophers''. In a modern sense, a philosopher is an intellectual who contributes to one or more branches of philosophy, such as aesthetics, ethics, epistemology, philosophy of science, logic, metaphysics, social theory, philosophy of religion, and political philosophy. A philosopher may also be someone who has worked in the hum ...

Acoustics
Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an Acoustical engineering, acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. Hearing (sense), Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound and hearing as a key element of mating rituals or for marking territories. Art, ...

Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by th ...
