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 history and culture. The English identity is of History of Anglo-Saxon England, Anglo-Saxon origin, when they were known in Old English as the ('race or tribe of the Angles'). Their ethnonym is derived from the Angles, one of the Germanic peoples who migrated to Great Britain around the 5th century AD. The English largely descend from two main historical population groups the West Germanic tribes (the Angles, Saxons, Jutes and Frisians) who settled in southern Britain following the withdrawal of the Ancient Rome, Romans, and the Romano-British culture, partially Romanised Celtic Britons already living 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. From Westminster School Aylesbury passed in 1598 to Christ Church, Oxford, where he took the degrees of B.A. and M.A. in 1602 and 1605, respectively. On leaving college he was appointed secretary to Charles Howard, 1st Earl of Nottingham, lord high admiral of England. He was continued in the post by George Villiers, 1st Duke of Buckingham, Nottingham's successor (1619), who befriended him actively, procuring for him the additional offices of one of the masters of requests with, from 19 April 1627, the title of baronet. He was Surveyor of the Navy from 1628 for four years, and naval commissioner inspecting the fleet at Portsmo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circulation Of The Blood
The blood circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek ''kardia'' meaning ''heart'', and from Latin ''vascula'' meaning ''vessels''). The circulatory system has two divisions, a systemic circulation or circuit, and a pulmonary circulation or circuit. Some sources use the terms ''cardiovascular system'' and ''vascular system'' interchangeably with the ''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 circulatory system is closed in vertebrates, which means that the blood never leaves the network of blood vessels. Some invertebrates such as arthro ...

William Harvey
William Harvey (1 April 1578 – 3 June 1657) was an English physician who made influential contributions in anatomy and physiology. He was the first known physician to describe completely, and in detail, the systemic circulation and properties 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 of the theory. 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 of a wall of the dining room at Rolls Park, Chig ... [...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 is perhaps best known as the author of the ''Brief Lives'', his collection of short biographical pieces. 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 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antilogarithm
In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a number to the base is the exponent to which must be raised, to produce . For example, since , the ''logarithm base'' 10 of is , or . The logarithm of to ''base'' is denoted as , or without parentheses, , or even without the explicit base, , when no confusion is possible, or when the base does not matter such as in big O notation. The logarithm base is called the decimal or common logarithm and is commonly used in science and engineering. The natural logarithm has the number e (mathematical constant), as its base; its use is widespread in mathematics and physics, because of its very simple derivative. The binary logarithm uses base and is frequently used in computer science. Logarithms were introduced by John Napier in 1614 as a means of simplifying calculations. They were rapidly adopted by navigators, scientists, engineers, surveyors and oth ... [...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. Early life He was born at Southwick in Sussex. 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 Briggs and other mathematicians. He was promoted by seniority to M.A. in 1630 and taught in the short-lived Chichester Academy set up by Samuel Hartlib. On 3 July 1632 he married Ithamaria Reginald (also rendered as Ithamara or Ithuma ... [...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] |
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 ...
