Paulos offers a hilarious account of how the stock market both follows and defies mathematical principals. He offers an engaging overview of everything from 'betas' to the efficient market hypothesis.

In A Mathematician Plays the Stock Market best-selling author John Allen Paulos demonstrates what the tools of mathematics can tell us about the vagaries of the stock market. Employing his trademark stories, vignettes, paradoxes, and puzzles (and even a film treatment), Paulos addresses every thinking reader's curiosity about the market: Is it efficient? Is it rational? Is there anything to technical analysis, fundamental analysis, and other supposedly time-tested methods of picking stocks? How can one quantify risk? What are the most common scams? What light do fractals, network theory, and common psychological foibles shed on investor behavior? Are there any approaches to investing that truly outperform the major indexes? Can a deeper knowledge of mathematics help beat the odds? All of these questions are explored with the engaging erudition that made Paulos's A Mathematician Reads the Newspaper and Innumeracy favorites with both armchair mathematicians and readers who want to think like them. Paulos also shares the cautionary tale of his own long and disastrous love affair with WorldCom. In the tradition of Burton Malkiel's A Random Walk Down Wall Street and Jeremy Siegel's Stocks for the Long Run, this wry and illuminating book is for anyone, investor or not, who follows the markets-or knows someone who does.

TOT EL QUE VOLIES SABER DEL MÓN DE LES PLANTES I NO T'ATREVIES A PREGUNTAR Arribem a casa i... altre cop, la planta pansida... Potser és que no en sabem prou de relacionar-nos amb el món vegetal o que ens fa massa por... fracassar. Pero el mon de les plantes pot ser mes senzill i mes ame del que a vegades ens imaginem. No cal ser una avia experta o haver fet un master en tecniques vegetals per establir una relacio fructifera amb un gerani o una clivia. Nomes cal tenir-ne ganes i estar disposat a convertir la jardineria en una practica tan divertida i excitant com el ball, el sexe o l'esport. Des de l'aigua que necessiten fins a l'adob que els va millor o les darreres tecniques d'estalvi d'aigua, aquest llibre de Silvia Bures, especialista i innovadora en el sector, es un manual per a tots els publics, fresc i modern, ple d'idees i suggeriments per conviure amb les nostres plantes. Pero no nomes aixo: el llibre s'endinsa en els tipus de plantes, la seva historia, les modes que es generen, les aplicacions que tenen, les curiositats i els mites que les envolten, el cultiu dels horts urbans i, fins i tot, les solucions que les plantes ens ofereixen en temps de crisi... Un cop l'hagueu llegit, ja podreu dir allo de a mi no se'm moren les plantes. CONSULTORI DE SILVIA BURES A LA VANGUARDIA [http://www.lavanguardia....

A wonderful tale of love loss and community with folklore and magic I adored it LIZ FENWICK A town in need An extraordinary cat A season for miracles It s nearly Christmas and committed Londoner Mina Kestle is close to signing a deal that will make her career and give her everything she s ever wanted And then she receives a mysterious letter in the post along with an ancient key sent by her long estranged godfather Davy Penhallow is an artist who lives on the tiny Cornish island of Morgelyn with only his pet cat Murr for company Mina hasn t seen or heard from him in decades but now it seems he wants her to look after his cottage and his cat while he recovers from a stroke in hospital Mina doesn t know why Davy has written after all these years but she intends to do what s right sort out the cottage and the cat and then get back to London in time for her career saving meeting before everything she s built comes crashing down around her But the more time Mina spends in the cottage looking after Murr and remembering the magic of Cornish folklore the harder it becomes for her to tear herself away And when she discovers that a set of ruthless property developers are coming for Morgelyn she realises she might be the only one who can

Critical phenomena is one of the most exciting areas of modern physics. This book provides a thorough but economic introduction into the principles and techniques of the theory of critical phenomena and the renormalization group, from the perspective of modern condensed matter physics. Assuming basic knowledge of quantum and statistical mechanics, the book discusses phase transitions in magnets, superfluids, superconductors, and gauge field theories. Particular attention is given to modern topics such as gauge field fluctuations in superconductors, the Kosterlitz-Thouless transition, duality transformations, and quantum phase transitions - all of which are at the forefront of today''s physics research. This book contains numerous problems of varying degrees of difficulty, with solutions. These problems provide readers with a wealth of material to test their understanding of the subject. It is ideal for graduate students and more experienced researchers in the fields of condensed matter physics, statistical physics, and many-body physics. Has a straightforward and economic style of presentation allowing readers to quickly get to the essence of the material Includes a modern selection of topics including several not found in other books Contains fully solved and original problems

The importance and the beauty of modern quantum field theory resides in the power and variety of its methods and ideas, which find application in domains as different as particle physics, cosmology, condensed matter, statistical mechanics and critical phenomena. This book introduces the reader to the modern developments, assuming no previous knowledge of quantum field theory. Along with standard topics like Feynman diagrams, the book discusses effective lagrangians, renormalization group equations, the path integral formulation, spontaneous symmetry breaking and non-abelian gauge theories. The inclusion of more advanced topics will also make this a most useful book for graduate students and researchers.

This long awaited monograph deals with the fascinating group of plants known as geraniums or cranesbills. It is restricted to the plants covered by the scientific name Geranium, but does not include those plants known in English as geranium which botanists have transferred to the genus Pelargonium. The book is the result of 28 years of research by the author. It is lavishly illustrated with maps, line drawings and photographs. There is a gap in the available botanical literatura covering the geraniums. The last monographic treatment by Reinhard Knuth appeared in 1912. In the intervening years, much taxonomic information has been accumulated, rendering this massive and comprehensive work out of date. There have been many new species discoveries and much research has been conducted for revisional works. All these changes have caused much confussion to the outsider, making the need for a comprehensive monograph even more pressing. For each of the 307 species covered in this book, complete synonymy and detailed description is given, as well as its distribution, relationships, variability and taxonomic history are discussed. Each species is provided with a map showing its known distribution based on specimens examined by the author, and is illustrated with line drawings and, if available, with colour photographs based on reliable specimens. Some introductory sections explain in detail the morphological structure of these plants, chromosome numbers, breeding system, phytochemistry, distribution, habitats and relationships. For practical reasons and to facilitate the identification of the species, four identification keys have been prepared that cover respectively North and Central America, South America, the Pacific area and the Old World species. This book will be of value to botanists, but also for specialists hobbyists and to anyone fascinated by these plants.
