William George Horner
William George Horner (9 June 1786 – 22 September 1837) was a British mathematician. Proficient in classics; mathematics, he was a schoolmaster, headmaster and schoolkeeper, who wrote extensively on functional equations, number theory and approximation theory, but also on optics. His contribution to approximation theory is honoured in the designation Horner's method, in particular respect of a paper in ''Philosophical Transactions of the Royal Society of London'' for 1819. The modern invention of the zoetrope, under the name ''Daedaleum'' in 1834, has been attributed to him. Horner died comparatively young, before the establishment of specialist, regular scientific periodicals. So, the way others have written about him has tended to diverge, sometimes markedly, from his own prolific, if dispersed, record of publications and the contemporary reception of them. Family life The eldest son of the Rev. William Horner, a Wesleyan minister, Horner was born in Bristol. He was educate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George William Horner
George William Horner (1849–1930) was a British biblical scholar, an editor of the text of the New Testament in the dialects of the Coptic language. In the Bohairic version, Horner edited in four volumes from 1898 to 1905. In the Sahidic version, he edited in 7 volumes from 1911 to 1924. Another area of his interest was the liturgy of the Coptic and Ethiopic Church. The text of the four Gospels, in the Bohairic edition, was established on the basis of Huntington MS 17; the Pauline epistles, Catholic epistles and the Acts of the Apostles on the basis of Oriental MS 424 and the Apocalypse, on Curzon MS 128.

Leonhard Euler
Leonhard Euler ( , ; 15 April 170718 September 1783) was a Swiss mathematician, physicist, astronomer, geographer, logician and engineer who founded the studies of graph theory and topology and made pioneering and influential discoveries in many other branches of mathematics such as analytic number theory, complex analysis, and infinitesimal calculus. He introduced much of modern mathematical terminology and notation, including the notion of a mathematical function. He is also known for his work in mechanics, fluid dynamics, optics, astronomy and music theory. Euler is held to be one of the greatest mathematicians in history and the greatest of the 18th century. A statement attributed to Pierre-Simon Laplace expresses Euler's influence on mathematics: "Read Euler, read Euler, he is the master of us all." Carl Friedrich Gauss remarked: "The study of Euler's works will remain the best school for the different fields of mathematics, and nothing else can replace it." Euler is a ...

Optics Horner
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be acc ...
