Wilhelm Ludwig
Wilhelm Ludwig (20 October 1901, in Asch, Austria-Hungary (now Aš, Czech Republic) – 23 January 1959, in Leipzig, East Germany) was a German zoologist and geneticist. His research interests were population genetics, inbreeding, paternity diagnosis, evolution, biometrics, sensory physiology (optimal Horopter), sex ratio in humans and animals and the right-left problem. Life and work Wilhelm Ludwig was born as the son of Wolfgang Ludwig (1855–1919) and Josepha Katharina Taumer (1855–1919). He studied zoology, chemistry and mathematics at the universities of Leipzig, Kiel, and Freiburg with professor Johannes Meisenheimer. He earned his doctorate with a thesis about the "Copulation apparatus of stink bugs". By 1930, he was in habilitation at the Berthold Klatt in Halle at Berthold Klatt with works on the "Theory of ciliary movement". At the University of Halle, he worked with the zoologist . From 1938, onwards he worked in Halle as a professor. At the suggestion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austria-Hungary
Austria-Hungary, often referred to as the Austro-Hungarian Empire,, the Dual Monarchy, or Austria, was a constitutional monarchy and great power in Central Europe between 1867 and 1918. It was formed with the Austro-Hungarian Compromise of 1867 in the aftermath of the Austro-Prussian War and was dissolved shortly after its defeat in the First World War. Austria-Hungary was ruled by the House of Habsburg and constituted the last phase in the constitutional evolution of the Habsburg monarchy. It was a multinational state and one of Europe's major powers at the time. Austria-Hungary was geographically the second-largest country in Europe after the Russian Empire, at and the third-most populous (after Russia and the German Empire). The Empire built up the fourth-largest machine building industry in the world, after the United States, Germany and the United Kingdom. Austria-Hungary also became the world's third-largest manufacturer and exporter of electric home appliances, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drosophila
''Drosophila'' () is a genus of flies, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or (less frequently) pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit. They should not be confused with the Tephritidae, a related family, which are also called fruit flies (sometimes referred to as "true fruit flies"); tephritids feed primarily on unripe or ripe fruit, with many species being regarded as destructive agricultural pests, especially the Mediterranean fruit fly. One species of ''Drosophila'' in particular, ''D. melanogaster'', has been heavily used in research in genetics and is a common model organism in developmental biology. The terms "fruit fly" and "''Drosophila''" are often used synonymously with ''D. melanogaster'' in modern biological literature. The entire genus, however, contains more than 1,500 species and is very diverse in appearance, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mathematical And Theoretical Biology
Mathematical and theoretical biology, or biomathematics, is a branch of biology which employs theoretical analysis, mathematical models and abstractions of the living organisms to investigate the principles that govern the structure, development and behavior of the systems, as opposed to experimental biology which deals with the conduction of experiments to prove and validate the scientific theories. The field is sometimes called mathematical biology or biomathematics to stress the mathematical side, or theoretical biology to stress the biological side. Theoretical biology focuses more on the development of theoretical principles for biology while mathematical biology focuses on the use of mathematical tools to study biological systems, even though the two terms are sometimes interchanged. Mathematical biology aims at the mathematical representation and modeling of biological processes, using techniques and tools of applied mathematics. It can be useful in both theoretical and prac ...

Erich Von Holst
Erich Walther von Holst (28 November 1908 – 26 May 1962) was a German behavioral physiologist who was a Baltic German native of Riga, Livonia and was related to historian Hermann Eduard von Holst (1841–1904). In the 1950s he founded the Max Planck Institute for Behavioral Physiology at Seewiesen, Bavaria. Background Holst is remembered for his work with zoologist Konrad Lorenz (1903–1989) concerning the processes of endogenous generation of stimuli and of central coordination as a basis of behavioral physiology. This idea refuted the existing "reflex theory" which stated that this behavior was based on a chain of reflexes. Holst postulated that the basic central nervous configuration consisted of a "cell" permanently producing endogenous stimulation, but prevented from activating its effector by another "cell" that also produced endogenous stimulation which contained an inhibition effect. This inhibiting "second cell" was influenced by the receptor, and stopped ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mainz
Mainz () is the capital and largest city of Rhineland-Palatinate, Germany. Mainz is on the left bank of the Rhine, opposite to the place that the Main (river), Main joins the Rhine. Downstream of the confluence, the Rhine flows to the north-west, with Mainz on the left bank, and Wiesbaden, the capital of the neighbouring state Hesse, on the right bank. Mainz is an independent city with a population of 218,578 (as of 2019) and forms part of the Frankfurt Rhine-Main, Frankfurt Rhine-Main Metropolitan Region. Mainz was founded by the Roman Empire, Romans in the 1st century BC as a military fortress on the northernmost frontier of the empire and provincial capital of Germania Superior. Mainz became an important city in the 8th century AD as part of the Holy Roman Empire, capital of the Electorate of Mainz and seat of the Elector of Mainz, Archbishop-Elector of Mainz, the Primate (bishop), Primate of Germany.

Giessen
Giessen, spelled Gießen in German (), is a town in the German state (''Bundesland'') of Hesse, capital of both the district of Giessen and the administrative region of Giessen. The population is approximately 90,000, with roughly 37,000 university students. The name comes from ''Giezzen'', as it was first referred to in 1197, which refers to the position of the town between several rivers, lakes and streams. The largest river in Giessen is the Lahn, which divides the town in two parts (west and east), roughly north of Frankfurt am Main. Giessen is also home to the University of Giessen. In 1969, the town hosted the ninth ''Hessentag'' state festival. History Giessen came into being as a moated castle in 1152 built by Count Wilhelm von Gleiberg, although the history of the community in the northeast and in today's suburb called "Wieseck" dates back to 775. The town became part of Hesse-Marburg in 1567, passing to Hesse-Darmstadt in 1604. The University of Giessen was founded i ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
