Manfred Von Ardenne
Manfred baron von Ardenne (; 20 January 190726 May 1997) was a German researcher, autodidact in applied physics, and an inventor. He took out approximately 600 patents in fields including electron microscopy, medical technology, nuclear technology, plasma physics, and radio and television technology. From 1928 to 1945, he directed his self-funded and private research laboratory ''Forschungslaboratorium für Elektronenphysik'', where he developed and invented many techniques used in modern physics. After the World War II, von Ardenne was held in Soviet custody and was one of many of the German nuclear physicists in the former Soviet program of nuclear weapons, and later honored with the Stalin Prize by the former Soviet Union. Upon his return to the then East Germany, he started another German company law, private engineering firm, ''Forschungsinstitut Manfred von Ardenne''. Ardenne is seen as one of the main inventors of the television. Career Early years The stormy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Autodidacticism
Autodidacticism (also autodidactism) or self-education (also self-learning, self-study and self-teaching) is the practice of education without the guidance of schoolmasters (i.e., teachers, professors, institutions). Overview Autodidacts are ''self-taught'' humans who learn a subject-of-study's aboutness through self-study. This educative praxis (process) may involve, complement, or be an alternative to formal education. Formal education itself may have a hidden curriculum that requires self-study for the uninitiated. Generally, autodidacts are individuals who choose the subject they will study, their studying material, and the studying rhythm and time. Autodidacts may or may not have formal education, and their study may be either a complement or an alternative to formal education. Many notable contributions have been made by autodidacts. The self-learning curriculum is infinite. One may seek out alternative pathways in education and use these to gain compet ...

Elisabeth Von Ardenne
''Effi Briest'' () is a realist novel by Theodor Fontane. Published in book form in 1895, ''Effi Briest'' marks both a watershed and a climax in the poetic realism of literature. It can be thematically compared to other novels on 19th-century marriage from a female perspective, such as ''Anna Karenina'' and ''Madame Bovary'', which are also adultery tragedies. Plot introduction Seventeen-year-old Effi Briest, the daughter of a German aristocrat, is married off to 38-year-old Baron Geert von Innstetten, who courted her mother Luise and was spurned for his status, which he has now improved. Plot summary Effi Briest, who is attracted by social status, moves to the fictional Pomeranian port of Kessin (loosely modeled on Swinemünde). Her husband Innstetten is away for weeks at a time, and Effi, who is shunned by local nobles, finds but one friend. Her suspicions that their house may be haunted are not entirely laid to rest by Innstetten. When she says there may be a ghost, he deri ...

German Company Law
German company law (''Gesellschaftsrecht'') is an influential legal regime for companies in Germany. The primary form of company is the public company or (AG). A private company with limited liability is known as a (GmbH). A partnership is called a ''Kommanditgesellschaft'' (KG). History In Germany, through most of the 19th century the ''Kommanditgesellschaft'' (''société en commandite'' in France) was the typical form of business organisation. A "KG" had at least one member with unlimited liability, but other investors' liability was limited to their contribution. A special concession was not required for setting up this company. The first German public company statute was the Prussian Act of 1794. In 1861 the ''Allgemeines Deutsches Handelsgesetzbuch'' or the General Commercial Code for all of Germany, as well as Austria, was enacted, which devoted a section to joint stock companies. This allowed incorporation with limited liability. Companies would be constituted with a sing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Germany
East Germany, officially known as the German Democratic Republic (GDR), was a country in Central Europe from Foundation of East Germany, its formation on 7 October 1949 until German reunification, its reunification with West Germany (FRG) on 3 October 1990. Until 1989, it was generally viewed as a communist state and described itself as a Socialist state, socialist "workers' and peasants' state". The Economy of East Germany, economy of the country was Central planning, centrally planned and government-owned corporation, state-owned. Although the GDR had to pay substantial war reparations to the Soviets, its economy became the most successful in the Eastern Bloc.

Forced Labor In Nazi Concentration Camps
Forced labor was an important and ubiquitous aspect of the Nazi concentration camps which operated in Nazi Germany and German-occupied Europe between 1933 and 1945. It was the harshest and most inhumane part of a larger system of forced labor in Nazi Germany. Origins Traditionally, prisoners were often deployed in penal labor performing unskilled work. During the first years of Nazi Germany's existence, unemployment was high and forced labor in the concentration camps was presented as re-education through labor and a means of punishing offenders. Nazi propaganda idolized work, in contrast to the view of work as punishment. Prisoners in early camps were forced to perform economically valueless but strenuous tasks, such as farming on moorland (for example at Esterwegen concentration camp, Esterwegen). Other prisoners had to work on constructing and expanding the camps. German state governments complained at being required to pay the upkeep of the camps, which was eventually take ...

Independent Scientist
An independent scientist (historically also known as gentleman scientist) is a financially independent scientist who pursues scientific study without direct affiliation to a public institution such as a university or government-run research and development body. The term "gentleman scientist" arose in post-Renaissance Europe, but became less common in the 20th century as government and private funding increased. Most independent scientists have at some point in their career been affiliated with some academic institution, such as Charles Darwin, who was affiliated with the Geological Society of London. History Self-funded scientists practiced more commonly from the Renaissance until the late 19th century, including the Victorian era, especially in England, before large-scale government and corporate funding was available. Many early fellows of the Royal Society in London were independent scientists. Modern Modern-day independent scientists who fund their own research on an i ...

Plasma Physics
Plasma () is a state of matter characterized by the presence of a significant portion of charged particles in any combination of ions or electrons. It is the most abundant form of ordinary matter in the universe, mostly in stars (including the Sun), but also dominating the rarefied intracluster medium and intergalactic medium. Plasma can be artificially generated, for example, by heating a neutral gas or subjecting it to a strong electromagnetic field. The presence of charged particles makes plasma electrically conductive, with the dynamics of individual particles and macroscopic plasma motion governed by collective electromagnetic fields and very sensitive to externally applied fields. The response of plasma to electromagnetic fields is used in many modern devices and technologies, such as plasma televisions or plasma etching. Depending on temperature and density, a certain number of neutral particles may also be present, in which case plasma is called partially ioni ...

Nuclear Technology
Nuclear technology is technology that involves the nuclear reactions of atomic nucleus, atomic nuclei. Among the notable nuclear technologies are nuclear reactors, nuclear medicine and nuclear weapons. It is also used, among other things, in smoke detectors and gun sights. History and scientific background Discovery The vast majority of common, natural phenomena on Earth only involve gravity and electromagnetism, and not nuclear reactions. This is because atomic nuclei are generally kept apart because they contain positive electrical charges and therefore repel each other. In 1896, Henri Becquerel was investigating phosphorescence in uranium salts when he discovered a new phenomenon which came to be called radioactivity. He, Pierre Curie and Marie Curie began investigating the phenomenon. In the process, they isolated the element radium, which is highly radioactive. They discovered that radioactive materials produce intense, penetrating rays of three distinct sorts, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Technology
Health technology is defined by the World Health Organization as the "application of organized knowledge and skills in the form of devices, medicines, vaccines, procedures, and systems developed to solve a health problem and improve quality of lives". This includes pharmaceuticals, devices, procedures, and organizational systems used in the healthcare industry, as well as computer-supported information systems. In the United States, these technologies involve standardized physical objects, as well as traditional and designed social means and methods to treat or care for patients. Development Pre-digital era During the pre-digital era, patients suffered from inefficient and faulty clinical systems, processes, and conditions. Many medical errors happened in the past due to undeveloped health technologies. Some examples of these medical errors included adverse drug events and alarm fatigue. When many alarms are repeatedly triggered or activated, especially for unimportant events ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
