Józef Maria Hoene-Wroński
Józef Maria Hoene-Wroński (; ; ; 23 August 1776 – 9 August 1853) was a Polish messianist philosopher, mathematician, physicist, inventor, lawyer, occultist and economist. In mathematics, he is known for introducing a novel series expansion for a function in response to Joseph Louis Lagrange's use of infinite series. The coefficients in Wroński's new series form the Wronskian, a determinant Thomas Muir named in 1882. As an inventor, he is credited with designing some of the first caterpillar vehicles. Life and work He was born as ''Hoëné'' in 1776 but changed his name in 1815 to Józef Wroński. Later in life he changed his name to Józef Maria Hoene-Wroński, without using his family's original French spelling Hoëné. At no point in his life, neither in Polish or French, was he known as Hoëné-Wroński; nor was the common French transliteration, Josef Hoëné-Wronski, ever his official name in his native Poland (though it might have served as his chosen French ''nom ...

Wolsztyn
Wolsztyn () is a town in western Poland, on the western edge of Greater Poland Voivodeship. It is the seat of Wolsztyn County, and of the smaller administrative district of Gmina Wolsztyn. Geography The town is situated within the historic Greater Poland region, located on the small Dojca river, a headstream of the Obra, about southwest of Poznań. The municipal area includes a large lake ('; Wolsztyn Lake), next to which is a palace built in Classical style in the early 20th century, now used as a hotel and restaurant, and a park. Nearby tourist destinations include the Pszczew Landscape Park and the Przemęt Landscape Park. History The current settlement was established about 1285 on a causeway across the swampy Dojca River, probably by Cistercian monks descending from Obra Abbey. It developed as a centre of wool trade and cloth manufacturing on the road from Poznań to Lusatia, vested with market rights in 1424. Wolsztyn's town privileges were confirmed in 1519. It ...

French Philosophy
French philosophy, here taken to mean philosophy in the French language, has been extremely diverse and has influenced Western philosophy as a whole for centuries, from the medieval scholasticism of Peter Abelard, through the founding of modern philosophy by René Descartes, to 20th century philosophy of science, existentialism, phenomenology, structuralism, and postmodernism. Medieval period Peter Abelard Peter Abelard (1079–1142) was a scholastic philosopher, theologian and logician. The story of his affair with and love for Héloïse has become legendary. The '' Chambers Biographical Dictionary'' describes him as "the keenest thinker and boldest theologian of the 12th Century".'' Chambers Biographical Dictionary'', 2011, , page 3 The general importance of Abelard lies in his having fixed more decisively than anyone before him the scholastic manner of philosophizing, with the object of giving a formally rational expression to received ecclesiastical doctrine. However his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continuous Track
Continuous track or tracked treads are a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tyres on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking. Modern continuous tracks can be made with soft belts of synthetic rubber, reinforced with steel wires, in the case of lighter agricultural machinery. The more common classical type is a solid chain track made of steel plates (with or without rubber pads), also called caterpillar tread or tank tread, which is preferred for robust and heavy construction vehicles and military vehicles. The prominent treads of the metal plates are both hard-wearing and damage resistant, especially in comparison to rubber tyres. The aggressive treads of the t ...

Thomas Muir (mathematician)
Sir Thomas Muir (25 August 1844 – 21 March 1934) was a Scottish mathematician, remembered as an authority on determinants. Life He was born in Stonebyres in South Lanarkshire, and brought up in the small town of Biggar. He was educated at Wishaw Public School. At the University of Glasgow he changed his studies from classics to mathematics after advice from the future Lord Kelvin. After graduating he held positions at the University of St Andrews and the University of Glasgow. From 1874 to 1892 he taught at Glasgow High School. In 1882 he published ''Treatise on the theory of determinants''; then in 1890 he published a ''History of determinants''. In his 1882 work, Muir rediscovered an important lemma that was first proved by Cayley 35 years earlier: In Glasgow he lived at Beechcroft in the Bothwell district. In 1874 he was elected a Fellow of the Royal Society of Edinburgh, His proposers were William Thomson, Lord Kelvin, Hugh Blackburn, Philip Kelland and Pete ...

Determinant
In mathematics, the determinant is a Scalar (mathematics), scalar-valued function (mathematics), function of the entries of a square matrix. The determinant of a matrix is commonly denoted , , or . Its value characterizes some properties of the matrix and the linear map represented, on a given basis (linear algebra), basis, by the matrix. In particular, the determinant is nonzero if and only if the matrix is invertible matrix, invertible and the corresponding linear map is an linear isomorphism, isomorphism. However, if the determinant is zero, the matrix is referred to as singular, meaning it does not have an inverse. The determinant is completely determined by the two following properties: the determinant of a product of matrices is the product of their determinants, and the determinant of a triangular matrix is the product of its diagonal entries. The determinant of a matrix is :\begin a & b\\c & d \end=ad-bc, and the determinant of a matrix is : \begin a & b & c \\ d & e ...

Occultist
The occult () is a category of esoteric or supernatural beliefs and practices which generally fall outside the scope of organized religion and science, encompassing phenomena involving a 'hidden' or 'secret' agency, such as magic and mysticism. It can also refer to paranormal ideas such as extra-sensory perception and parapsychology. The term occult sciences was used in 16th-century Europe to refer to astrology, alchemy, and natural magic. The term occultism emerged in 19th-century France, among figures such as Antoine Court de Gébelin. It came to be associated with various French esoteric groups connected to Éliphas Lévi and Papus, and in 1875 was introduced into the English language by the esotericist Helena Blavatsky. Throughout the 20th century, the term 'occult' was used idiosyncratically by a range of different authors. By the 21st century the term 'occultism' was commonly employed –including by academic scholars in the field of Western esotericism studie ...

Inventor
An invention is a unique or novel device, method, composition, idea, or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand-alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain. An inventor creates or discovers an invention. The word ''inventor'' comes from the Latin verb ''invenire'', ''invent-'', to find. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers or scientists. The ideation process may be augmented by the applications of algorithms and methods from the domain collectively known as artificial intelligence . Some inventions can be patented. The system of patents wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
