Robert Ellis Dudgeon
Robert Ellis Dudgeon (17 March 1820 – 8 September 1904) was a Scottish homeopath. Life Born at Leith on 17 March 1820, Dudgeon was a younger son of a timber merchant and shipowner there. After attending a private school he received his medical education at Edinburgh, partly in the university and partly in the extra-academical medical school. Having received the licence of the Royal College of Surgeons of Edinburgh in 1839, he attended lectures in Paris, by Velpeau, Andral, Louis, and others. He graduated M.D. at Edinburgh on 1 August 1841, and spent a semester at Vienna under Škoda, Rokitansky, Hebra, and Jäger. At Vienna fellow students John Drysdale and Rutherfurd Russell paid attention to fashionable homœopathic practice, developed by Samuel Hahnemann some forty years before; but Dudgeon was not at the time attracted by Hahnemann's system. From Vienna he went to Berlin to study diseases of the eye under Jüngken, of the ear under Kramer, and organic chemistry unde ...

Homeopath
Homeopathy or homoeopathy is a pseudoscientific system of alternative medicine. It was conceived in 1796 by the German physician Samuel Hahnemann. Its practitioners, called homeopaths, believe that a substance that causes symptoms of a disease in healthy people can cure similar symptoms in sick people; this doctrine is called '' similia similibus curentur'', or "like cures like". Homeopathic preparations are termed ''remedies'' and are made using homeopathic dilution. In this process, the selected substance is repeatedly diluted until the final product is chemically indistinguishable from the diluent. Often not even a single molecule of the original substance can be expected to remain in the product. Between each dilution homeopaths may hit and/or shake the product, claiming this makes the diluent remember the original substance after its removal. Practitioners claim that such preparations, upon oral intake, can treat or cure disease. All relevant scientific knowledge about ...

William Stokes (physician)
William Stokes (1 October 1804 – 10 January 1878) was an Irish physician, who was Regius Professor of Physic at the University of Dublin. He graduated from the University of Edinburgh Medical School with an MD in 1825 later returning the practice in Dublin at Meath Hospital. He went on to create two important works on cardiac and pulmonary diseases – ''A Treatise on the Diagnosis and Treatment of Diseases of the Chest'' (1837) and ''The Diseases of the Heart and Aorta'' (1854) – as well as one of the first treatises on the use of the stethoscope. He emphasised the importance of clinical examination in forming diagnoses, and of ward-based learning for students of medicine. Both Cheyne–Stokes breathing (the alternation of apnoea with tachypnoea) and Stokes–Adams syndrome are named after him. ''Stokes' sign'' is a severe throbbing in the abdomen, at the right of the umbilicus, in acute enteritis. ''Stokes law'' is that a muscle situated above an inflamed membrane i ...

Erewhon
''Erewhon: or, Over the Range'' () is a novel by English writer Samuel Butler, first published anonymously in 1872, set in a fictional country discovered and explored by the protagonist. The book is a satire on Victorian society. The first few chapters of the novel dealing with the discovery of Erewhon are in fact based on Butler's own experiences in New Zealand, where, as a young man, he worked as a sheep farmer on Mesopotamia Station for about four years (1860–64), and explored parts of the interior of the South Island and wrote about in his ''A First Year in Canterbury Settlement'' (1863). The novel is one of the first to explore ideas of artificial intelligence, as influenced by Darwin's recently published ''On the Origin of Species'' (1859) and the machines developed out of the Industrial Revolution (late 18th to early 19th centuries). Specifically, it concerns itself, in the three-chapter "Book of the Machines", with the potentially dangerous ideas of machine con ...

Sir James Mackenzie
Sir James Mackenzie (12 April 1853 – 26 January 1925) was a Scottish cardiologist who was a pioneer in the study of cardiac arrhythmias. Due to his work in the cardiac field he is known as a research giant in primary care, and was knighted by King George V in 1915. Biography James Mackenzie was born at Pictonhill in Scone, where his father was a farmer. He left school at Perth Academy aged 14 and was apprenticed to a chemist. In 1873 he was offered a partnership in the chemist's firm but turned it down in order to study medicine. After private tuition in Latin he passed his entrance examination for the University of Edinburgh in October 1874 and qualified as a doctor in 1878. After completing his residency in Edinburgh, Mackenzie became a general practitioner in borough of Burnley in Lancashire, England where he continued to practice medicine for more than a quarter of a century. While he was engaged in a busy practice, he made many original observations, completed his MD deg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sphygmograph
The sphygmograph ( ) was a mechanical device used to measure blood pressure in the mid-19th century. It was developed in 1854 by German physiologist Karl von Vierordt (1818–1884). It is considered the first external, non-intrusive device used to estimate blood pressure. The device was a system of levers hooked to a scale-pan in which weights were placed to determine the amount of external pressure needed to stop blood flow in the radial artery. Although the instrument was cumbersome and its measurements imprecise, the basic concept of Vierordt's sphygmograph eventually led to the blood pressure cuff used today. In 1863, Étienne-Jules Marey (1830–1904) improved the device by making it portable. Also he included a specialized instrument to be placed above the radial artery that was able to magnify pulse waves and record them on paper with an attached pen. In 1872, Frederick Akbar Mahomed published a description of a modified sphygmograph. This modified version made the sphygmo ...

Accommodation Of The Eye
Accommodation is the process by which the vertebrate eye changes optical power to maintain a clear image or focus on an object as its distance varies. In this, distances vary for individuals from the far point—the maximum distance from the eye for which a clear image of an object can be seen, to the near point—the minimum distance for a clear image. Accommodation usually acts like a reflex, including part of the accommodation-vergence reflex, but it can also be consciously controlled. Mammals, birds and reptiles vary their eyes' optical power by changing the form of the elastic lens using the ciliary body (in humans up to 15 dioptres in the mean). Fish and amphibians vary the power by changing the distance between a rigid lens and the retina with muscles. The young human eye can change focus from distance (infinity) to as near as 6.5 cm from the eye. This dramatic change in focal power of the eye of approximately 15 dioptres (the reciprocal of focal length in metres) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Refraction
In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction. How much a wave is refracted is determined by the change in wave speed and the initial direction of wave propagation relative to the direction of change in speed. For light, refraction follows Snell's law, which states that, for a given pair of media, the ratio of the sines of the angle of incidence ''θ1'' and angle of refraction ''θ2'' is equal to the ratio of phase velocities (''v''1 / ''v''2) in the two media, or equivalently, to the refractive indices (''n''2 / ''n''1) of the two media. :\frac =\frac=\frac Optical prisms and lenses use refraction to redirect light, as does the human eye. The refractive index of materials varies with the wavelengt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Fuchs (doctor)
Ernst Fuchs (14 June 1851, in Vienna – 21 November 1930, in Vienna) was an Austrian ophthalmologist, physician and researcher. Overview The importance of Fuchs' life achievement must surely be based on his discovery and description of numerous ocular diseases and abnormalities. As a result of more than 250 scientific publications, the name Ernst Fuchs became well known throughout the world. Although his name is commonly recognized in conjunction with various corneal and anterior segment disorders, Ernst Fuchs' contribution to ophthalmology exceeds purely the delineation of ocular diseases and the detailed description of signs. Fuchs' collection of microscopic samples laid the foundation for anatomical and pathological understanding of blood vessels, muscles, and most other tissues of the eye. Additionally, Fuchs was able to pass on his unique knowledge, educating ophthalmologists at an international level. His Textbook of Ophthalmology was, for many decades, the most extensivel ...

The Organon Of The Healing Art
''Organon of the Art of Healing'' (''Organon der rationellen Heilkunde'') by Samuel Hahnemann, 1810, laid out the doctrine of his ideas of homoeopathy. The work was repeatedly revised by Hahnemann and published in six editions, with the name changed from the second onwards to Organon of Medicine (''Organon der Heilkunst''),UK Parliamentary Committee Science and Technology Committee "Evidence Check 2: Homeopathy"/ref> and has been so since the mid-19th century. as reprinted in The Book Hahnemann wrote this book in order to document his new system of medicine, "Homoeopathy". In 1796, some six years after Hahnemann first experienced the effect of Peruvian Bark Cinchona in 1790 he published an article under the title "Essay on a New Principle". After conducting personal observations and experiments, Hahnemann published his new account of homoeopathy in book form in 1810. The original title of the book was ''Organon of Rational Art of Healing''. In 1819, the second edition was publishe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Willesden
Willesden () is an area of northwest London, situated 5 miles (8 km) northwest of Charing Cross. It is historically a parish in the county of Middlesex that was incorporated as the Municipal Borough of Willesden in 1933, and has formed part of the London Borough of Brent in Greater London since 1965. Dollis Hill is also sometimes referred to as being part of Willesden. With its close proximity to affluent neighbourhoods Brondesbury Park, Queen's Park and Kensal Rise, the area surrounding Willesden Green station has seen increased gentrification in the past several years, with rapidly rising property prices. ''The Daily Telegraph'' called Willesden Green one of London's "new middle class" areas. The area has a population of 44,295 as of 2011 including the Willesden Green, Dollis Hill and Dudden Hill wards.
