Carl Ludwig Schleich
Carl Ludwig Schleich (19 July 1859 – 7 March 1922) was a German surgeon and writer. He is best known for his contribution to clinical anesthesia. In addition, he was also a philosopher, poet and painter. Biography Family Schelich's ancestors were a Munich family of prominent painters who had moved to Freienwalde. They included Robert Schleich and Eduard Schleich the Elder. Early life From a very early age, Schleich was exposed to a background in biology. His father was very interested in natural history and the leading theories in the epoch. Later Schleich would recall: In the year 1864, Graefe was a guest in my father's house during the historic conference of biologists, at which Darwin, Haeckel, and Virchow were the mutually hostile protagonists. I, alas, who was only five years of age, was not even aware of this earth-shaking event, since I was lying unconscious in the grip of meningitis. In his childhood, he frequently heard "extremely vigorous" debates about th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Berlin
Humboldt-Universität zu Berlin (german: Humboldt-Universität zu Berlin, abbreviated HU Berlin) is a German public research university in the central borough of Mitte in Berlin. It was established by Frederick William III on the initiative of Wilhelm von Humboldt, Johann Gottlieb Fichte and Friedrich Ernst Daniel Schleiermacher as the University of Berlin () in 1809, and opened in 1810, making it the oldest of Berlin's four universities. From 1828 until its closure in 1945, it was named Friedrich Wilhelm University (german: Friedrich-Wilhelms-Universität). During the Cold War, the university found itself in East Berlin and was ''de facto'' split in two when the Free University of Berlin opened in West Berlin. The university received its current name in honour of Alexander and Wilhelm von Humboldt in 1949. The university is divided into nine faculties including its medical school shared with the Freie Universität Berlin. The university has a student enrollment of around ...

Science And Religion
The relationship between religion and science involves discussions that interconnect the study of the natural world, history, philosophy, and theology. Even though the ancient and medieval worlds did not have conceptions resembling the modern understandings of "science" or of "religion", certain elements of modern ideas on the subject recur throughout history. The pair-structured phrases "religion and science" and "science and religion" first emerged in the literature during the 19th century. This coincided with the refining of "science" (from the studies of "natural philosophy") and of "religion" as distinct concepts in the preceding few centuries—partly due to professionalization of the sciences, the Protestant Reformation, colonization, and globalization. Since then the relationship between science and religion has been characterized in terms of "conflict", "harmony", "complexity", and "mutual independence", among others. Both science and religion are complex social and cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Struggle For Existence
The concept of the struggle for existence concerns the competition or battle for resources needed to live. It can refer to human society, or to organisms in nature. The concept is ancient, and the term ''struggle for existence'' was in use by the end of the 18th century. From the 17th century onwards the concept was associated with a population exceeding resources, an issue shown starkly in Thomas Robert Malthus’ ''An Essay on the Principle of Population'' which drew on Benjamin Franklin's ''Observations Concerning the Increase of Mankind, Peopling of Countries, etc.''. Charles Darwin used the phrase "struggle for existence" in a broader sense, and chose the term as the title to the third chapter of ''On the Origin of Species'' published in 1859. Using Malthus's idea of the struggle for existence, Darwin was able to develop his view of adaptation, which was highly influential in the formulation of the theory of natural selection.Ospovat, Dov.

Capital (economics)
In economics, capital goods or capital are "those durable produced goods that are in turn used as productive inputs for further production" of goods and services. At the macroeconomic level, "the nation's capital stock includes buildings, equipment, software, and inventories during a given year." A typical example is the machinery used in factories. Capital can be increased by the use of the factors of production, which however excludes certain durable goods like homes and personal automobiles that are not used in the production of saleable goods and services. Adam Smith defined capital as "that part of man's stock which he expects to afford him revenue". In economic models, capital is an input in the production function. The total physical capital at any given moment in time is referred to as the capital stock (not to be confused with the capital stock of a business entity). Capital goods, real capital, or capital assets are already-produced, durable goods or any non-fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Materialism
Materialism is a form of philosophical monism which holds matter to be the fundamental substance in nature, and all things, including mental states and consciousness, are results of material interactions. According to philosophical materialism, mind and consciousness are by-products or epiphenomena of material processes (such as the biochemistry of the human brain and nervous system), without which they cannot exist. This concept directly contrasts with idealism, where mind and consciousness are first-order realities to which matter is dependent while material interactions are secondary. Materialism is closely related to physicalism—the view that all that exists is ultimately physical. Philosophical physicalism has evolved from materialism with the theories of the physical sciences to incorporate more sophisticated notions of physicality than mere ordinary matter (e.g. spacetime, physical energies and forces, and dark matter). Thus, the term ''physicalism'' is preferred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Rowohlt
Ernst R. Rowohlt (23 June 1887 in Bremen – 1 December 1960 in Hamburg) was a German publisher who founded the Rowohlt publishing house in 1908 and headed it and its successors until his death. In 1912 he married actress Emmy Reye, but the marriage only lasted a short while. In 1921 he married Hilda Pangust and in 1957 he married Maria Pierenkämper. Rowohlt had two sons, both illegitimate: Heinrich Maria Ledig-Rowohlt (1908–1992), who succeeded him as head of the publishing house, and Harry Rowohlt (1945–2015), a writer. He also had one daughter. As a publisher he specialized in works by American authors including Ernest Hemingway and William Faulkner. With the rise of the Nazis he switched to safer non-fiction and travel works, and in 1937 joined the Nazi party. He insisted on keeping his Jewish staff and editors and remained publisher for officially disapproved writers such as Hans Fallada. In 1936 he allowed Jewish author Bruno Adler to publish a biography of Adalbert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hysteria
Hysteria is a term used colloquially to mean ungovernable emotional excess and can refer to a temporary state of mind or emotion. In the nineteenth century, hysteria was considered a diagnosable physical illness in women. It is assumed that the basis for diagnosis operated under the belief that women are predisposed to mental and behavioral conditions; an interpretation of sex-related differences in stress responses. In the twentieth century, it shifted to being considered a mental illness. Many influential people such as Sigmund Freud and Jean-Martin Charcot dedicated research to hysteria patients. Currently, most doctors practicing medicine do not accept hysteria as a medical diagnosis. The blanket diagnosis of hysteria has been fragmented into myriad medical categories such as epilepsy, histrionic personality disorder, conversion disorders, dissociative disorders, or other medical conditions. Furthermore, lifestyle choices, such as choosing not to wed, are no longer consid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neuron
A neuron, neurone, or nerve cell is an electrically excitable cell that communicates with other cells via specialized connections called synapses. The neuron is the main component of nervous tissue in all animals except sponges and placozoa. Non-animals like plants and fungi do not have nerve cells. Neurons are typically classified into three types based on their function. Sensory neurons respond to stimuli such as touch, sound, or light that affect the cells of the sensory organs, and they send signals to the spinal cord or brain. Motor neurons receive signals from the brain and spinal cord to control everything from muscle contractions to glandular output. Interneurons connect neurons to other neurons within the same region of the brain or spinal cord. When multiple neurons are connected together, they form what is called a neural circuit. A typical neuron consists of a cell body (soma), dendrites, and a single axon. The soma is a compact structure, and the axon and dend ...

Nervous System
In biology, the nervous system is the highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. Nervous tissue first arose in wormlike organisms about 550 to 600 million years ago. In vertebrates it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord. The PNS consists mainly of nerves, which are enclosed bundles of the long fibers or axons, that connect the CNS to every other part of the body. Nerves that transmit signals from the brain are called motor nerves or '' efferent'' nerves, while those nerves that transmit information from the body to the CNS are called sensory nerves or '' afferent''. Spinal nerves are mixed nerves that serve both fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glial Cells
Glia, also called glial cells (gliocytes) or neuroglia, are non-neuronal cells in the central nervous system (brain and spinal cord) and the peripheral nervous system that do not produce electrical impulses. They maintain homeostasis, form myelin in the peripheral nervous system, and provide support and protection for neurons. In the central nervous system, glial cells include oligodendrocytes, astrocytes, ependymal cells, and microglia, and in the peripheral nervous system they include Schwann cells and satellite cells. Function They have four main functions: *to surround neurons and hold them in place *to supply nutrients and oxygen to neurons *to insulate one neuron from another *to destroy pathogens and remove dead neurons. They also play a role in neurotransmission and synaptic connections, and in physiological processes such as breathing. While glia were thought to outnumber neurons by a ratio of 10:1, recent studies using newer methods and reappraisal of historical quan ...
