Excerpt: Pachaiyappa's College, Trinity College, CambridgeSrnivsa Aiyangr Rmnujan FRS, better known as Srinivasa Iyengar Ramanujan (Tamil: ) (22 December 1887 26 April 1920) was an Indian mathematician and autodidact who, with almost no formal training in pure mathematics, made substantial contributions to mathematical analysis, number theory, infinite series and continued fractions. Born and raised in Erode, Tamil Nadu, India, Ramanujan first encountered formal mathematics at age 10. He demonstrated a natural ability, and was given books on advanced trigonometry written by S L Loney. He had mastered them by age 12, and even discovered theorems of his own. He demonstrated unusual mathematical skills at school, winning accolades and awards. By 17, Ramanujan conducted his own mathematical research on Bernoulli numbers and the EulerMascheroni constant. He received a scholarship to study at Government College in Kumbakonam, but lost it when he failed his non-mathematical coursework. He joined another college to pursue independent mathematical research, working as a clerk in the Accountant-General's office at the Madras Port Trust Office to support himself. In 19121913, he sent samples of his theorems to three academics at the University of Cambridge. Only G. H. Hardy recognized the brilliance of his work, subsequently inviting Ramanujan to...More: http://booksllc.net/?id=47717 ... Read more

Excerpt: Part of a series of articles on (sometimes written pi) is a mathematical constant whose value is the ratio of any circle's circumference to its diameter in Euclidean space; this is the same value as the ratio of a circle's area to the square of its radius. It is approximately equal to 3.141593 in the usual decimal notation. The constant is also known as Archimedes' Constant, after Archimedes of Syracuse, although this name for the constant is uncommon in modern, western, English-speaking contexts. Many formulae from mathematics, science, and engineering involve , which is one of the most important mathematical and physical constants. Unlike many physical constants, pi is a dimensionless quantity, meaning that it is simply a number without physical units. is an irrational number, which means that its value cannot be expressed exactly as a fraction m/n, where m and n are integers. Consequently, its decimal representation never ends or repeats. It is also a transcendental number, which implies, among other things, that no finite sequence of algebraic operations on integers (powers, roots, sums, etc.) can...More: http://booksllc.net/?id=23601 ...

Ramanujan travailla principalement en théorie analytique des nombres et devint célèbre pour ses formules sommatoires impliquant des constantes telles que π et e, des nombres premiers et la fonction partage d'un entier obtenue avec Godfrey Harold Hardy. Ramanujan avait un raisonnement très rapide, ce qui faisait dire à certains de ses contemporains qu'il était un mathématicien « naturel », voire un génie. Ramanujan est né à Erode, dans l'actuel État de Tamil Nadu en Inde, dans une famille de brâhmanes pauvre et orthodoxe. Il était un autodidacte et resta toujours très autonome. Il apprit les mathématiques à partir de deux uniques livres qu'il s'était procurés avant ses 15 ans : La Trigonométrie plane de S. Looney, et Synopsis of Elementary Results in Pure Mathematics de S. Carr qui contenait une liste de quelques 6 000 théorèmes sans démonstration. Ces deux ouvrages lui permirent d'établir une grande quantité de résultats sur la théorie des nombres, les fonctions elliptiques, les fractions continues et les séries infinies, tout en créant son propre système de représentation symbolique pour arriver à ces résultats. Jugeant son entourage académique dépassé, il publia plusieurs articles dans les journaux mathématiques indiens et tenta alors d'intéresser les mathéma...http://booksllc.net/?l=fr ... Read more

Product Description
This book contains essays on Ramanujan and his work , as well as important survey articles in areas influenced by Ramanujan's mathematics. Most of the articles in the book are nontechnical, but even those that are more technical contain substantial sections that will engage the general reader.

The book opens with the only four existing photographs of Ramanujan, presenting historical accounts and information about other people in the photos. This section includes an account of a cryptic family history written by his younger brother, S. Lakshmi Narasimhan. Following are articles on Ramanujan's illness by R. A. Rankin, the British physician D. A. B. Young, and Nobel laureate S. Chandrasekhar. They present a study of his symptoms, a convincing diagnosis of the cause of his death, and a thorough exposition of Ramanujan's life as a patient in English sanitariums and nursing homes.

Following this are biographies of S. Janaki (Mrs. Ramanujan) and S. Narayana Iyer, Chief Accountant of the Madras Port Trust Office, who first communicated Ramanujan's work to the Journal of the Indian Mathematical Society. The last half of the book begins with a section on "Ramanujan's Manuscripts and Notebooks". Included is an important article by G. E. Andrews on Ramanujan's lost notebook.

The final two sections feature both nontechnical articles, such as Jonathan and Peter Borwein's "Ramanujan and pi", and more technical articles by Freeman Dyson, Atle Selberg, Richard Askey, and G. N. Watson.

This volume complements the book Ramanujan: Letters and Commentary, Volume 9, in the AMS series, History of Mathematics. For more on Ramanujan, see these AMS publications, Ramanujan: Twelve Lectures on Subjects Suggested by His Life and Work, Volume 136.H, and Collected Papers of Srinivasa Ramanujan, Volume 159.H, in the AMS Chelsea Publishing series.

A lucid mental portrait of genius
If anything, these books will make you feel stupid. The quickness of Ramanujan's mind is astounding-- as he delves into the most contemplative and intuitive cognitive adventures one can possibly imagine. I have alwaysthought mathematics to be the purest of mental languages, due to itsclarity and exactitude; Ramanujan is an artist of the highest caliber forhis creative expression of this form. Close analysis of the text willreveal much about how he truly thought: a very unorthodox intuition mixedwith an almost suprahuman numeric prescience. These notebooks are highlyrecommended to EVERYONE, regardless of mathematical skill level. If youdont, you will regret it and feel super-dumbo. ... Read more
