Walter Warner
Walter Warner (1563–1643) was an English mathematician and scientist. Life He was born in Leicestershire and educated at Merton College, Oxford, graduating B.A. in 1578. Andrew Pyle (editor), ''Dictionary of Seventeenth Century British Philosophers'' (2000), article Warner, pp. 858–86 See also Jan Prins: Walter Warner (ca. 1557-1643) and his notes on Animal Organisms. Dissertation, Utrecht University, 1992/ref> At the end of the sixteenth century he belonged to the circle round Henry Percy, 9th Earl of Northumberland, the 'Wizard Earl'. The Earl's ‘three magi’ were Warner, Thomas Harriot and Robert Hues. Percy paid Warner a retainer to help him with alchemical experiments (£20 per annum in 1595, rising to £40 in 1607). He also belonged to the overlapping group around Sir Walter Ralegh. At this time he was mainly known for chemical and medical interests. It has been argued by Jean Jacquot that this group of experimental researchers, sponsored by Percy and Rale ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English People
The English people are an ethnic group and nation native to England, who speak the English language in England, English language, a West Germanic languages, West Germanic language, and share a common ancestry, history, and culture. The English identity began with the History of Anglo-Saxon England, Anglo-Saxons, when they were known as the , meaning "Angle kin" or "English people". Their ethnonym is derived from the Angles (tribe), Angles, one of the Germanic peoples who invaded Great Britain, Britain around the 5th century AD. The English largely descend from two main historical population groups: the West Germanic tribes, including the Angles, Saxons, and Jutes who settled in England and Wales, Southern Britain following the withdrawal of the Ancient Rome, Romans, and the Romano-British culture, partially Romanised Celtic Britons who already lived there.Martiniano, R., Caffell, A., Holst, M. et al.

Sir Thomas Aylesbury, 1st Baronet
Sir Thomas Aylesbury, 1st Baronet (1576 – 1657) was an English civil servant, Surveyor of the Navy from 1628 and jointly Master of the Mint from 1635, and a patron of mathematical learning. He was the great-grandfather of two British queens, Mary II and Anne. Life He was born in London in 1576, the second son of William Aylesbury and Anne Poole, his wife.

Circulation Of The Blood
In vertebrates, the circulatory system is a organ system, system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek meaning ''heart'', and Latin meaning ''vessels''). The circulatory system has two divisions, a systemic circulation, systemic circulation or circuit, and a pulmonary circulation, pulmonary circulation or circuit. Some sources use the terms ''cardiovascular system'' and ''vascular system'' interchangeably with ''circulatory system''. The network of blood vessels are the great vessels of the heart including large elastic arteries, and large veins; other arteries, smaller arterioles, capillaries that join with venules (small veins), and other veins. The Closed circulatory system, circulatory system is closed in vertebrates, which means that the blood never leaves the network of blood vessels. Many in ...

William Harvey
William Harvey (1 April 1578 – 3 June 1657) was an English physician who made influential contributions to anatomy and physiology. He was the first known physician to describe completely, and in detail, pulmonary and systemic circulation as well as the specific process of blood being pumped to the brain and the rest of the body by the heart (though earlier writers, such as Realdo Colombo, Michael Servetus, and Jacques Dubois, had provided precursors to some of his theories). Family William's father, Thomas Harvey, was a jurat of Folkestone where he served as mayor in 1600. Records and personal descriptions delineate him as an overall calm, diligent, and intelligent man whose sons “... revered, consulted and implicitly trusted in him...” (they) made their father the treasurer of their wealth when they acquired great estates...(He) kept, employed, and improved their gainings to their great advantage." Thomas Harvey's portrait can still be seen in the central panel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Aubrey
John Aubrey (12 March 1626 – 7 June 1697) was an English antiquary, natural philosopher and writer. He was a pioneer archaeologist, who recorded (often for the first time) numerous megalithic and other field monuments in southern England, and who is particularly noted for his systematic examination of the Avebury henge monument. The Aubrey holes at Stonehenge are named after him, although there is considerable doubt as to whether the holes that he observed are those that currently bear the name. He was also a pioneer folklorist, collecting together a miscellany of material on customs, traditions and beliefs under the title "Remaines of Gentilisme and Judaisme". He set out to compile county histories of both Wiltshire and Surrey, although both projects remained unfinished. His "Interpretation of Villare Anglicanum" (also unfinished) was the first attempt to compile a full-length study of English place-names. He had wider interests in applied mathematics and astronomy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antilogarithm
In mathematics, the logarithm of a number is the exponent by which another fixed value, the base, must be raised to produce that number. For example, the logarithm of to base is , because is to the rd power: . More generally, if , then is the logarithm of to base , written , so . As a single-variable function, the logarithm to base is the inverse of exponentiation with base . The logarithm base is called the ''decimal'' or ''common'' logarithm and is commonly used in science and engineering. The ''natural'' logarithm has the number as its base; its use is widespread in mathematics and physics because of its very simple derivative. The ''binary'' logarithm uses base and is widely used in computer science, information theory, music theory, and photography. When the base is unambiguous from the context or irrelevant it is often omitted, and the logarithm is written . Logarithms were introduced by John Napier in 1614 as a means of simplifying calculations. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Pell (mathematician)
John Pell (1 March 1611 – 12 December 1685) was an English mathematician and political agent abroad. He was made Royal Chair of Mathematics at Orange College by the Prince of Orange, and was under the patronage of Sir Charles Cavendish. He was also a compeer and correspondent of René Descartes and Thomas Hobbes. Early life He was born at Southwick in West Sussex, England. His father, also named John Pell, was from Southwick, and his mother was Mary Holland, from Halden in Kent. The second of two sons, Pell's older brother was Thomas Pell. By the time he was six, they were orphans, their father dying in 1616 and their mother the following year. John Pell the elder had a fine library, which proved valuable to the young Pell as he grew up. He was educated at Steyning Grammar School and entered Trinity College, Cambridge, at the age of 13. During his university career he became an accomplished linguist; even before taking a B.A. degree in 1629, he corresponded with Henry B ...

Refraction
In physics, refraction is the redirection of a wave as it passes from one transmission medium, 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 Wind wave, 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. Optical Prism (optics), prisms and Lens (optics), lenses use refraction to redirect light, as does the human eye. The refractive index of materials varies with the wavelength of light,R. Paschotta, article ochromatic dispersion in th, accessed on 2014-09-08 and thus the angle of the refraction also varies correspondingly. This is called dispersion (optics), dispersion and causes prism (optics), prisms and rainbows to divide white light into its constituent spectral ...

Welbeck Academy
The Welbeck Academy or Welbeck Circle is a name that has been given to the loose intellectual grouping around William Cavendish, 1st Duke of Newcastle-upon-Tyne in the first half of the 17th century. It takes its name from Welbeck Abbey, a country house in Nottinghamshire that was a Cavendish family seat. Another term used is Newcastle Circle.A. P. Martinich, ''Hobbes: A Biography'', pp. 98–102. The geographical connection is, however, more notional than real; and these terms have been regarded also as somewhat misleading. Cavendish was Viscount Mansfield in 1620, and moved up the noble ranks to Duke, step by step; "Newcastle" applies by 1628. Newcastle was a royalist exile in continental Europe in the latter part of the First English Civil War and the Interregnum. He then returned to England and lived to 1676. His life shows many instances of cultural and intellectual patronage. Science and mathematics A scientific interest was optics. The group involved in these studies incl ...
