Science
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

Area
Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or ''plane area'' refers to the area of a shape A shape or figure is a graphics, graphical representation of an object or its external boundary, outline, or external Surface (mathematics), surface, as opposed to other properties such as color, Surface texture, texture, or material type. A pl ... or planar lamina, while ''surface area'' refers to the area of an open surface or the boundary (mathematics), boundary of a solid geometry, three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analogue of the length of a plane curve, curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept). The area of a shape can be measured by com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johannes Peter Müller
Johannes Peter Müller (14 July 1801 – 28 April 1858) was a German physiologist, comparative anatomy, comparative anatomist, ichthyology, ichthyologist, and herpetology, herpetologist, known not only for his discoveries but also for his ability to synthesize knowledge. The paramesonephric duct (Müllerian duct) was named in his honor. Life Early years and education Müller was born in Koblenz, Coblenz. He was the son of a poor shoemaker, and was about to be apprenticed to a saddler when his talents attracted the attention of his teacher, and he prepared himself to become a Roman Catholic Priest. During his Secondary school, college course in Koblenz, he devoted himself to the classics and made his own translations of Aristotle. At first, his intention was to become a priest. When he was eighteen, his love for natural science became dominant, and he turned to medicine, entering the University of Bonn in 1819. There he received his Doctor of Medicine, M.D. in 1822. He then studie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arteriosclerosis
Arteriosclerosis is the thickening, hardening, and loss of elasticity of the walls of Artery, arteries. This process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis, which is a specific form of arteriosclerosis caused by the buildup of fatty plaques, cholesterol, and some other substances in and on the artery walls. It can be brought on by smoking, a bad diet, or many genetic factors. Atherosclerosis is the primary cause of coronary artery disease (CAD) and stroke, with multiple genetic and environmental contributions. Genetic-epidemiologic studies have identified a long list of genetic and non-genetic risk factors for CAD. However, such studies indicate that family history is the most significant independent risk factor. Signs and symptoms The signs and symptoms of arteriosclerosis depend on the vessel affected by the disease. If affecting cerebral or ophthalmic vessels, as in cerebrovascular accid ...

Jean Lobstein
Jean Georges Chrétien Frédéric Martin Lobstein (German spelling: Johann Friedrich Georg Christian Martin Lobstein) (8 May 1777 – 7 March 1835) was a German-born, French pathologist and surgeon who was a native of Giessen. He was the nephew of noted surgeon Johann Friedrich Lobstein (1736-1784).

In 1819 he attained a professorship in pathological anatomy. Jean Lobstein is remembered for contributions made in the field of pathological anatomy. He coined the term 'osteoporosis.' He also described a disorder known today as osteogenesis imperfecta type I, which is sometimes called "Lobstein's disease". This d ...

Marshall Hall (physiologist)
Marshall Hall FRS (18 February 1790 – 11 August 1857) was an English physician, physiologist and early neurologist. His name is attached to the theory of reflex arc mediated by the spinal cord, to a method of resuscitation of drowned people, and to the elucidation of function of capillary vessels. Biography Hall was born on 18 February 1790 at Basford, near Nottingham, England, where his father, Robert Hall, was a cotton manufacturer. He was a brother of the inventor Samuel Hall. Having attended the Rev. J. Blanchard's academy at Nottingham, he entered a chemists shop at Newark-on-Trent, and in 1809 began to study medicine at Edinburgh University. In 1811 he was elected senior president of the Royal Medical Society; the following year he took the M.D. degree, and was immediately appointed resident house physician to the Edinburgh Royal Infirmary. This appointment he resigned after two years, when he visited Paris and its medical schools, and, on a walking tour, those al ...

Natural Theology
Natural theology, once also termed physico-theology, is a type of theology that seeks to provide arguments for theological topics (such as the existence of a deity) based on reason and the discoveries of science. This distinguishes it from revealed theology, which is based on scripture and/or religious experiences, also from transcendental theology, which is based on ''a priori'' reasoning. It is thus a type of philosophy, with the aim of explaining the nature of the celestial motors, or gods, or of one supreme god, that are responsible for heavenly motion. Aristotle's tractate on metaphysics claims to demonstrate the necessary existence of an unmoved prime mover. For monotheistic religions, this principally involves arguments about the attributes or non-attributes of a deity, and especially the deity's existence, using arguments that do not involve recourse to revelation. The ideals of natural theology can be traced back to the Old Testament and Greek philosophy. Ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
