    The clarity and eloquence of the presentation make it popular with teachers and students alike. The text aims to expand the reader's view of the field and to present standard material in a novel way. All of the most important topics in the field are covered with a fresh perspective, including iterative methods for systems of equations and eigenvalue problems and the underlying principles of conditioning and stability. Presentation is in the form of 40 lectures, which each focus on one or two central ideas. The unity between topics is emphasized throughout, with no risk of getting lost in details and technicalities. The book breaks with tradition by beginning with the QR factorization - an important and fresh idea for students, and the thread that connects most of the algorithms of numerical linear algebra.

    Devised in India in the 7th and 8th centuries and brought to North Africa by Muslim traders, the Hindu-Arabic system helped transform the West into the dominant force in science, technology, and commerce, leaving behind Muslim cultures which had long known it but had failed to see its potential.The young Italian, Leonardo of Pisa (better known today as Fibonacci), had learned the Hindu number system when he traveled to North Africa with his father, a customs agent. The book he created was Liber abbaci, the "Book of Calculation," and the revolution that followed its publication was enormous. Arithmetic made it possible for ordinary people to buy and sell goods, convert currencies, and keep accurate records of possessions more readily than ever before. Liber abbaci's publication led directly to large-scale international commerce and the scientific revolution of the Renaissance.Yet despite the ubiquity of his discoveries, Leonardo of Pisa remains an enigma. His name is best known today in association with an exercise in Liber abbaci whose solution gives rise to a sequence of numbers--the Fibonacci sequence--used by some to predict the rise and fall of financial markets, and evident in myriad biological structures.One of the great math popularizers of our time, Keith Devlin recreates the life and enduring legacy of an overlooked genius, and in the process makes clear how central numbers and mathematics are to our daily lives.

    The material is arranged chronologically beginning with archaic origins and covers Egyptian, Mesopotamian, Greek, Chinese, Indian, Arabic and European contributions done to the nineteenth century and present day.

    The idea is simple: to improve any aspect of your life, you must create the right atmosphere to support it. The Feng Shui Bible brings all the strands of this ancient practise into one simple, useable reference. The opening section explains the key concepts of feng shui, chi energy, yin and yang, the five elements and eight trigrams, and illustrates them with real life applications and examples. It also details the basic tools of feng shui - everyday objects like mirrors, plants, and fountains that help the energy in any space flow more easily. The comprehensive Feng Shui Directory explains how these principles can be used to improve every aspect of life - home, relationships, finances, creativity, career, health, and spiritual connection.

    These images are awesome not just for their beauty alone, but because they suggest an order underlying their growth, a harmony existing in nature. What does it mean that such an order exists; how far does it extend? The Power of Limits was inspired by those simple discoveries of harmony. The author went on to investigate and measure hundreds of patterns—ancient and modern, minute and vast. His discovery, vividly illustrated here, is that certain proportions occur over and over again in all these forms. Patterns are also repeated in how things grow and are made—by the dynamic union of opposites—as demonstrated by the spirals that move in opposite directions in the growth of a plant. The joining of unity and diversity in the discipline of proportional limitations creates forms that are beautiful to us because they embody the principles of the cosmic order of which we are a part; conversely, the limitlessness of that order is revealed by the strictness of its forms. The author shows how we, as humans, are included in the universal harmony of form, and suggests that the union of complementary opposites may be a way to extend that harmony to the psychological and social realms as well.

    In Rob Neyer's Big Book of Baseball Legends, Neyer breathes new life into both classic and obscure stories throughout twentieth-century baseball—stories that, while engaging on their own, also tell us fascinating things about their main characters and about the sport's incredibly rich history. With his signature style, Rob gets to the heart of every anecdote, working through the particulars with careful research drawn from a variety of primary sources. For each story, he asks: Did this really happen? Did it happen, sort of? Or was the story simply the wild invention of someone's imagination? Among the scores of legends Neyer questions and investigates... -Did an errant Bob Feller pitch really destroy the career of a National League All-Star? -Did Greg Maddux mean to give up a long blast to Jeff Bagwell? -Was Fred Lynn the clutch player he thinks he was? -Did Tommy Lasorda have a direct line to God? -Did Negro Leaguer Gene Benson really knock Indians second baseman Johnny Berardino out of baseball and into General Hospital? -Did Billy Martin really outplay Jackie Robinson every time they met? -Oh, and what about Babe Ruth's “Called Shot”?
