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 relativit ...

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 professorship. Conferment and roles A university faculty can confer the title to an academic who has a higher doctoral degree - usually in the form of a habilitation. The title, ''Privatdozent'', as such does not imply a sala ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Giessen Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

Special Relativity
In physics, the special theory of relativity, or special relativity for short, is a scientific theory regarding the relationship between space and time. In Albert Einstein's original treatment, the theory is based on two postulates: # The laws of physics are invariant (that is, identical) in all inertial frames of reference (that is, frames of reference with no acceleration). # The speed of light in vacuum is the same for all observers, regardless of the motion of the light source or the observer. Origins and significance Special relativity was originally proposed by Albert Einstein in a paper published on 26 September 1905 titled "On the Electrodynamics of Moving Bodies".Albert Einstein (1905)''Zur Elektrodynamik bewegter Körper'', ''Annalen der Physik'' 17: 891; English translatioOn the Electrodynamics of Moving Bodiesby George Barker Jeffery and Wilfrid Perrett (1923); Another English translation On the Electrodynamics of Moving Bodies by Megh Nad Saha (1920).

Inertial Frame Of Reference
In classical physics and special relativity, an inertial frame of reference (also called inertial reference frame, inertial frame, inertial space, or Galilean reference frame) is a frame of reference that is not undergoing any acceleration. It is a frame in which an isolated physical object — an object with zero net force acting on it — is perceived to move with a constant velocity (it might be a zero velocity) or, equivalently, it is a frame of reference in which Newton's laws of motion#Newton's first law, Newton's first law of motion holds. All inertial frames are in a state of constant, rectilinear motion with respect to one another; in other words, an accelerometer moving with any of them would detect zero acceleration. It has been observed that celestial objects which are far away from other objects and which are in uniform motion with respect to the Cosmic microwave background#Features, cosmic microwave background radiation maintain such uniform motion.

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
Psychiatric hospitals, also known as mental health hospitals, behavioral health hospitals, are hospitals or wards specializing in the treatment of severe mental disorders, such as schizophrenia, bipolar disorder, eating disorders, dissociative identity disorder, major depressive disorder and many others. Psychiatric hospitals vary widely in their size and grading. Some hospitals may specialize only in short-term or outpatient therapy for low-risk patients. Others may specialize in the temporary or permanent containment of patients who need routine assistance, treatment, or a specialized and controlled environment due to a psychiatric disorder. Patients often choose voluntary commitment, but those whom psychiatrists believe to pose significant danger to themselves or others may be subject to involuntary commitment and involuntary treatment. Psychiatric hospitals may also be called psychiatric wards/units (or "psych" wards/units) when they are a subunit of a regular hospital. ...

Neuropathy
Peripheral neuropathy, often shortened to neuropathy, is a general term describing disease affecting the peripheral nerves, meaning nerves beyond the brain and spinal cord. Damage to peripheral nerves may impair sensation, movement, gland, or organ function depending on which nerves are affected; in other words, neuropathy affecting motor, sensory, or autonomic nerves result in different symptoms. More than one type of nerve 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, exces ...

Photography
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purp ...
