Product Description
This is a story of more than a century ago, about a circle of young scientists, and in particular one among them, a mathematician, Niels Henrik Abel. He is well known to any mathematician of today; indeed, few men have their name associated with so many results and concepts in modern mathematics. This, however, is not the main concern in this book. It is rather the simple story of a scientist, his family and friends, his hopes and sorrows, his triumphs and tragedies. Many great lives, rich in outer events, have inspired biographers. But the profound humanity of a searching soul may provide the background for an equally arresting chronicle--the heart-warming tale of a young man who set out from a little Norwegian town to explore the world of science. ...

Product Description
Webster's bibliographic and event-based timelines are comprehensive in scope, covering virtually all topics, geographic locations and people. They do so from a linguistic point of view, and in the case of this book, the focus is on "Niels Henrik Abel," including when used in literature (e.g. all authors that might have Niels Henrik Abel in their name). As such, this book represents the largest compilation of timeline events associated with Niels Henrik Abel when it is used in proper noun form. Webster's timelines cover bibliographic citations, patented inventions, as well as non-conventional and alternative meanings which capture ambiguities in usage. These furthermore cover all parts of speech (possessive, institutional usage, geographic usage) and contexts, including pop culture, the arts, social sciences (linguistics, history, geography, economics, sociology, political science), business, computer science, literature, law, medicine, psychology, mathematics, chemistry, physics, biology and other physical sciences. This "data dump" results in a comprehensive set of entries for a bibliographic and/or event-based timeline on the proper name Niels Henrik Abel, since editorial decisions to include or exclude events is purely a linguistic process. The resulting entries are used under license or with permission, used under "fair use" conditions, used in agreement with the original authors, or are in the public domain. ... Read more

Mises à jour gratuites en ligne. Extrait : Niels Henrik Abel (né le 5 août 1802 à Frindoë près de Stavanger et mort le 6 avril 1829 à Christiania, aujourd'hui Oslo) est un mathématicien norvégien. Il est connu pour ses travaux en analyse mathématique sur la semi-convergence des séries numériques, des suites et séries de fonctions, les critères de convergence d'intégrale généralisée, sur la notion d'intégrale elliptique ; en algèbre, sur la résolution des équations. Abel, cadet d'une famille de sept enfants, passa ses premières années dans un pays frappé par la famine du fait du blocus continental, Napoléon ayant contraint les couronnes de Norvège et de Danemark à rejoindre sa coalition contre l'Angleterre. Son père, Sören Georg Abel, éduqua lui-même ses deux fils aînés jusqu'en 1815, puis les envoya au collège paroissial d'Oslo. Dans ce lycée, le latin, le grec et la religion étaient enseignés à l'ancienne, avec punitions et châtiments corporels. La situation évolua en 1817 à la suite du renvoi d'un professeur consécutif au décès d'un élève : le lycée recruta un jeune enseignant ouvert aux idées nouvelles et instruit de mathématiques, Bernt Michael Holmboe. Holmboë enseignait la mécanique céleste d'après Newton et Lalande. Découvrant l'intérêt de Niels Henrik pour les mathématiques, il lui obtint une bourse pour étudier à l'université (1820). Abel fréquenta cet établissement jusqu'en 1823. À la fin de cette année-là, il démontra que l'équation quelconque de degré cinq n'est pas résoluble à partir de combinaisons de racines des coefficients. Ces travaux suffirent à convaincre les...http://booksllc.net/?l=fr ... Read more

Product Description
High Quality Content by WIKIPEDIA articles! An abelian group, also called a commutative group, is a group in which the result of applying the group operation to two group elements does not depend on their order (the axiom of commutativity). Abelian groups generalize the arithmetic of addition of integers. They are named after Niels Henrik Abel. The concept of an abelian group is one of the first concepts encountered in undergraduate abstract algebra, with many other basic objects, such as a module and a vector space, being its refinements. The theory of abelian groups is generally simpler than that of their non-abelian counterparts, and finite abelian groups are very well understood. On the other hand, the theory of infinite abelian groups is an area of current research. ... Read more

Excerpt: Niels Henrik Abel (5 August 1802 - 6 April 1829) was a noted Norwegian mathematician who proved the impossibility of solving the quintic equation in radicals. Postcard of Gjerstad church and rectory in 1890-95. The main building of the rectory was the same as when Abel lived here. Niels Henrik Abel was born in Nedstrand, Norway, as second child to Søren Georg Abel and Anne Marie Simonsen. When he was born, the family was living at the rectory at Finnøy. Much suggests that Niels Henrik was born in the neighboring parish, as his parents were guests of the bailiff in Nedstrand in July / August of his year of birth. Niels Henrik Abel's father, Søren Georg Abel, had a degree in theology and philosophy and served as pastor at Finnøy. Søren's father, Niels's grandfather, Hans Mathias Abel, was also a pastor, at Gjerstad near Risør. Søren had spent his childhood at Gjerstad, and had also served as chaplain there; and after his father's death in 1804, Søren was appointed pastor at Gjerstad and the family moved there. Anne Marie Simonsen was from Risør; her father, Niels Henrik Saxild Simonsen, was a tradesman and...http://booksllc.net/?id=21573 ... Read more

Excerpt:"Abel's formula" redirects here. For the formula on difference operators, see Summation by parts . In mathematics , Abel's identity (also called Abel's differential equation identity ) is an equation that expresses the Wronskian of two homogeneous solutions of a second-order linear ordinary differential equation in terms of a coefficient of the original differential equation. The relation can be generalised to n -order linear ordinary differential equations. The identity is named after the Norwegian mathematician Niels Henrik Abel . Since Abel's identity relates the different linearly independent solutions of the differential equation, it can be used to find one solution from the other. It provides useful identities relating the solutions, and is also useful as a part of other techniques such as the method of variation of parameters . It is especially useful for equations such as Bessel's equation where the solutions do not have a simple analytical form, because in such cases the Wronskian is difficult to compute directly. A generalisation to first-order systems of homogeneous linear differential equations is given by Liouville's formula . Statement of Abel's identity Consider a homogeneous linear second-order ordinary differential equation on an interval I of the real line with a real - or complex -valued continuous function p . Abel's identity states that the Wronskian W ( y 1, y 2) of two real- or complex-valued solutions y 1 and y 2 of this differential equation, that is the function defined by the determinan... ...

Auszüge aus einer Rezension der englischen Ausgabe:
"Ein mathematisches Genie, das viel zu früh starb und das quasi erst auf dem Totenbett die Stelle angeboten bekam, die seinem Leben eine finanzielle Basis gegeben und ihm eine große Karriere eröffnet hätte... In der Mathematikgeschichte ist eine Biographie, aus der man leicht ein Film-Drehbuch machen könnte, kein Einzelfall (Galois, Ramanujan, ...), im vorliegenden Buch wird das Leben von Abel liebevoll und sehr ausführlich nachgezeichnet. Man kann das Buch als erste Einführung in die von Abel entwickelte Mathematik lesen. (Es gibt in dem Buch aber keine einzige Formel, wirklich schwierig wird es an keiner Stelle.) Es bietet auch die Möglichkeit, viel Interessantes aus der europäischen, insbesondere der norwegischen Geschichte zu Beginn des neunzehnten Jahrhunderts zu erfahren. ..."

Mark Twain once famously said "there was but one solitary thing about the past worth remembering, and that was the fact that it is past and can't be restored."  Well, over recent years, The British Library, working with Microsoft has embarked on an ambitious programme to digitise its collection of 19th century books.

There are now 65,000  titles available  (that's an incredible 25 million pages) of material ranging from works by famous names such as  Dickens, Trollope and Hardy as well as many forgotten literary gems , all of which can now be printed on demand and purchased right here on Amazon.
