Ludwig Lange (physicist)
Ludwig Lange (born 21 June 1863 in Gießen; died 12 July 1936 in Weinsberg) was a German physicist. Biography He was the son of the philologist and archaeologist Ludwig Lange and his wife Adelheide Blume. He studied mathematics, physics, and also psychology, epistemology, ethics at the University of Leipzig and the University of Gießen from 1882-1885. He was an assistant of Wilhelm Wundt from 1885-1887 and attained his Ph.D. in 1886. He worked for many years as a Privatdozent, and in the field of photography. From 1887 he exhibited growing symptoms of a nervous disease. In 1936 he died in a psychiatric hospital ( Klinikum am Weissenhof) in Weinsberg. Legacy Lange is known for inventing terms like inertial frame of reference and inertial time (1885), which were used by him instead of Newton's "absolute space and time". This was very important for the development of relativistic mechanics In physics, relativistic mechanics refers to mechanics compatible with special relativ ...

Privatdozent
''Privatdozent'' (for men) or ''Privatdozentin'' (for women), abbreviated PD, P.D. or Priv.-Doz., is an academic title conferred at some European universities, especially in German-speaking countries, to someone who holds certain formal qualifications that denote an ability (''facultas docendi'') and permission to teach ('' venia legendi'') a designated subject at the highest level. To be granted the title Priv.-Doz. by a university, a recipient has to fulfill the criteria set by the university which usually require excellence in research, teaching, and further education. In its current usage, the title indicates that the holder has completed their habilitation and is therefore granted permission to teach and examine students independently without having a full professorship (chair). With respect to the level of academic achievement, the title of ''Privatdozent'' is comparable to that of an Associate Professor (United States), Senior Lecturer (United Kingdom), or ''maître de con ...

Leipzig University Alumni
Leipzig (, ; ; Upper Saxon: ; ) is the most populous city in the German state of Saxony. The city has a population of 628,718 inhabitants as of 2023. It is the eighth-largest city in Germany and is part of the Central German Metropolitan Region. The name of the city is usually interpreted as a Slavic term meaning ''place of linden trees'', in line with many other Slavic placenames in the region. Leipzig is located about southwest of Berlin, in the southernmost part of the North German Plain (the Leipzig Bay), at the confluence of the White Elster and its tributaries Pleiße and Parthe. The Leipzig Riverside Forest, Europe's largest intra-city riparian forest, has developed along these rivers. Leipzig is at the centre of Neuseenland (''new lake district''). This district has several artificial lakes created from former lignite open-pit mines. Leipzig has been a trade city since at least the time of the Holy Roman Empire.

University Of Giessen Alumni
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in ...

Special Relativity
In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between Spacetime, space and time. In Albert Einstein's 1905 paper, Annus Mirabilis papers#Special relativity, "On the Electrodynamics of Moving Bodies", the theory is presented as being based on just Postulates of special relativity, two postulates: # The laws of physics are Invariant (physics), invariant (identical) in all Inertial frame of reference, inertial frames of reference (that is, Frame of reference, frames of reference with no acceleration). This is known as the principle of relativity. # The speed of light in vacuum is the same for all observers, regardless of the motion of light source or observer. This is known as the principle of light constancy, or the principle of light speed invariance. The first postulate was first formulated by Galileo Galilei (see ''Galilean invariance''). Background Special relativity builds upon important physics ide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Absolute Space And Time
Absolute space and time is a concept in physics and philosophy about the properties of the universe. In physics, absolute space and time may be a preferred frame. Early concept A version of the concept of absolute space (in the sense of a preferred frame) can be seen in Aristotelian physics. Robert S. Westman writes that a "whiff" of absolute space can be observed in Copernicus's '' De revolutionibus orbium coelestium'', where Copernicus uses the concept of an immobile sphere of stars. Newton Originally introduced by Sir Isaac Newton in '' Philosophiæ Naturalis Principia Mathematica'', the concepts of absolute time and space provided a theoretical foundation that facilitated Newtonian mechanics. According to Newton, absolute time and space respectively are independent aspects of objective reality: Absolute, true and mathematical time, of itself, and from its own nature flows equably without regard to anything external, and by another name is called duration: relative, appar ...

Inertial Frame Of Reference
In classical physics and special relativity, an inertial frame of reference (also called an inertial space or a Galilean reference frame) is a frame of reference in which objects exhibit inertia: they remain at rest or in uniform motion relative to the frame until acted upon by external forces. In such a frame, the laws of nature can be observed without the need to correct for acceleration. All frames of reference with zero acceleration are in a state of constant rectilinear motion (straight-line motion) with respect to one another. In such a frame, an object with zero net force acting on it, is perceived to move with a constant velocity, or, equivalently, Newton's laws of motion#Newton's first law, Newton's first law of motion holds. Such frames are known as inertial. Some physicists, like Isaac Newton, originally thought that one of these frames was absolute — the one approximated by the fixed stars. However, this is not required for the definition, and it is now known that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Klinikum Am Weissenhof
The Klinikum am Weissenhof is a psychiatric hospital in Weinsberg. It was opened in 1903 as a royal sanatorium on the public domain of Weißenhof. History Toward the end of the 19th century the four existing public sanatoria for the mentally ill in Württemberg (in Zwiefalten, Winnental, Schussenried and Weißenau) were overcrowded. Numerous invalids had to be rejected and accommodated in ordinary hospitals or sent back to their hometowns, where they could not be treated properly. There were no psychiatric institutions in the north of Württemberg, which was particularly problematic for the mentally ill and their relatives of those regions, since they had to travel large distances in order to receive treatment. In 1897/98 the federal state Wurttemberg wanted to build a fifth state owned psychiatric institute. The search for a suitable construction site started in the north of Wurtemberg. The site would have to be located in a quiet area on one hand, but at the same time it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychiatric Hospital
A psychiatric hospital, also known as a mental health hospital, a behavioral health hospital, or an asylum is a specialized medical facility that focuses on the treatment of severe Mental disorder, mental disorders. These institutions cater to patients with conditions such as schizophrenia, bipolar disorder, major depressive disorder, and Eating disorder, eating disorders, among others. Overview Psychiatric hospitals vary considerably in size and classification. Some specialize in short-term or outpatient therapy for low-risk patients, while others provide long-term care for individuals requiring routine assistance or a controlled environment due to their psychiatric condition. Patients may choose voluntary commitment, but those deemed to pose a significant danger to themselves or others may be subject to involuntary commitment and involuntary treatment, treatment. In general hospitals, psychiatric wards or units serve a similar purpose. Modern psychiatric hospitals have e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neuropathy
Peripheral neuropathy, often shortened to neuropathy, refers to damage or disease affecting the nerves. Damage to nerves may impair sensation, movement, gland function, and/or organ function depending on which nerve fibers are affected. Neuropathies affecting motor, sensory, or autonomic nerve fibers result in different symptoms. More than one type of fiber may be affected simultaneously. Peripheral neuropathy may be acute (with sudden onset, rapid progress) or chronic (symptoms begin subtly and progress slowly), and may be reversible or permanent. Common causes include systemic diseases (such as diabetes or leprosy), hyperglycemia-induced glycation, vitamin deficiency, medication (e.g., chemotherapy, or commonly prescribed antibiotics including metronidazole and the fluoroquinolone class of antibiotics (such as ciprofloxacin, levofloxacin, moxifloxacin)), traumatic injury, ischemia, radiation therapy, excessive alcohol consumption, immune system disease, celiac dis ...
