We often overlook the historical link between mathematics and technological advances, says Stewart—but this connection is integral to any complete understanding of human history.Equations are modeled on the patterns we find in the world around us, says Stewart, and it is through equations that we are able to make sense of, and in turn influence, our world. Stewart locates the origins of each equation he presents—from Pythagoras's Theorem to Newton's Law of Gravity to Einstein's Theory of Relativity—within a particular historical moment, elucidating the development of mathematical and philosophical thought necessary for each equation's discovery. None of these equations emerged in a vacuum, Stewart shows; each drew, in some way, on past equations and the thinking of the day. In turn, all of these equations paved the way for major developments in mathematics, science, philosophy, and technology. Without logarithms (invented in the early 17th century by John Napier and improved by Henry Briggs), scientists would not have been able to calculate the movement of the planets, and mathematicians would not have been able to develop fractal geometry. The Wave Equation is one of the most important equations in physics, and is crucial for engineers studying the vibrations in vehicles and the response of buildings to earthquakes. And the equation at the heart of Information Theory, devised by Claude Shannon, is the basis of digital communication today.An approachable and informative guide to the equations upon which nearly every aspect of scientific and mathematical understanding depends, In Pursuit of the Unknown is also a reminder that equations have profoundly influenced our thinking and continue to make possible many of the advances that we take for granted.

    Just about everyone has at least heard of Albert Einstein's formulation of 1905, which came into the world as something of an afterthought. But far fewer can explain his insightful linkage of energy to mass. David Bodanis offers an easily grasped gloss on the equation. Mass, he writes, "is simply the ultimate type of condensed or concentrated energy," whereas energy "is what billows out as an alternate form of mass under the right circumstances." Just what those circumstances are occupies much of Bodanis's book, which pays homage to Einstein and, just as important, to predecessors such as Maxwell, Faraday, and Lavoisier, who are not as well known as Einstein today. Balancing writerly energy and scholarly weight, Bodanis offers a primer in modern physics and cosmology, explaining that the universe today is an expression of mass that will, in some vastly distant future, one day slide back to the energy side of the equation, replacing the "dominion of matter" with "a great stillness"--a vision that is at once lovely and profoundly frightening. Without sliding into easy psychobiography, Bodanis explores other circumstances as well; namely, Einstein's background and character, which combined with a sterling intelligence to afford him an idiosyncratic view of the way things work--a view that would change the world. --Gregory McNamee

    But is his extraordinary intellect merely a gift of fiction, or can we learn to cultivate these abilities ourselves, to improve our lives at work and at home?We can, says psychologist and journalist Maria Konnikova, and in Mastermind she shows us how. Beginning with the "brain attic"--Holmes's metaphor for how we store information and organize knowledge--Konnikova unpacks the mental strategies that lead to clearer thinking and deeper insights. Drawing on twenty-first-century neuroscience and psychology, Mastermind explores Holmes's unique methods of ever-present mindfulness, astute observation, and logical deduction. In doing so, it shows how each of us, with some self-awareness and a little practice, can employ these same methods to sharpen our perceptions, solve difficult problems, and enhance our creative powers. For Holmes aficionados and casual readers alike, Konnikova reveals how the world's most keen-eyed detective can serve as an unparalleled guide to upgrading the mind.

    That is, until The Art and Power of Being a Lady‚ the book that brushes the cobwebs off and makes "lady" relevant to every girl and woman — whether her role model is Audrey Hepburn, Oprah Winfrey, Madeleine Albright, Lauryn Hill, or Mia Hamm. In an era when looking out for one another and taking the high road is too often lost in the shuffle, today's lady has not forgotten what's important. She is kind and considerate without being a doormat. She's assertive, but never a bully. She is sexy without being vulgar. She has great style but is never superficial. She gives back without asking for kudos. And from now on, the perfect word to describe her is "lady."

    The First Edition of this book was highly successful because it reconciled two schools of thought: it skillfully merged the best of traditional calculus with the best of the reform movement. This new edition continues to offer the balanced approach along with Stewart's hallmark features: meticulous accuracy, patient explanations, and carefully graded problems. The content has been refined and the examples and exercises have been updated. In addition, CALCULUS: CONCEPTS AND CONTEXTS, Second Edition now includes a free CD-ROM for students that contains animations, activities, and homework hints. The book integrates the use of the CD throughout by using icons that show students when to use the CD to deepen their understanding of a difficult concept.In CALCULUS: CONCEPTS AND CONTEXTS, this well respected author emphasizes conceptual understanding - motivating students with real world applications and stressing the Rule of Four in numerical, visual, algebraic, and verbal interpretations. All concepts are presented in the classic Stewart style: with simplicity, character, and attention to detail. In addition to his clear exposition, Stewart also creates well thought-out problems and exercises. The definitions are precise and the problems create an ideal balance between conceptual understanding and algebraic skills.

    But what about those with a wide array of interests, a dynamic curiosity about the world, and an ever-renewing wellspring of passions? Margaret Lobenstine calls these people “Renaissance Souls,” and in this groundbreaking book, she offers a life-planning strategy in tune with their dynamic, change-loving personalities. Renaissance Souls often get stuck, moving from entry-level job to entry-level job, degree to degree, or hobby to hobby, unwilling to settle on just one thing to do “for the rest of my life.” Or, after achieving success in one field, they yearn for new challenges and begin looking around for something different. Yet they are also afraid that if they pursue their changing interests, they will have to give up on financial security, becoming “a jack of all trades and master of none.”The Renaissance Soul, the first book devoted to this personality type, not only shows that it’s possible to design a successful, vibrant life built on multiple passions, but also gives readers the practical advice to do so. Lobenstine arms the reader with powerful life-design strategies, including how to:*Understand the exciting and powerful difference between choice and focus *Transform your day job so that it carries your dreams forward*Manage your time the Renaissance Soul way*Thrive on many interests without feeling scattered *Get paid for your passions*Learn a new field without going back to school*Get inspired by Renaissance Souls from ancient times to the present, from Leonardo da Vinci to Ben Franklin to Oprah WinfreyStocked with creative exercises, relevant resources, and interviews with successful Renaissance Souls, this profoundly inspiring guide will show readers the way to a richer, more fulfilling life—big enough to embrace all their dreams.

    Key questions and an amazingly clear "map" are now at your fingertips to begin your journey to "Live by Design." These are questions that, with the help of this book, you can answer and bring into action-oriented focus:What are the ten most defining moments of your life?What are the seven most critical choices you have made to put you on your current path?Who are the five most pivotal people in your world and how have they shaped you? Identifying and working with these key elements are at the heart of Dr. Phillip C. McGraw's latest work, Self Matters, and soon they will be at the heart of your own new work: you. Through his books, McGraw has changed the lives of millions. In introducing the world to his matter-of-fact, tell-it-like-it-is philosophy of life, Dr. Phil, as he is known to his legions of fans, has put an end to the "everyone's a victim" attitude that had taken hold of our culture. Published in over twenty-five countries, and with millions of books sold, his two number one bestsellers, Life Strategies and Relationship Rescue, forced readers to take a serious look at the excuses they had so long been clinging to as to why they were not happy, not successful, and not enjoying their one chance at living. Now, Dr. Phil takes those lessons a great leap further and explores one of the most challenging questions facing us all: When you look in the mirror, who is truly hiding beneath that face? Instead of taking a surface look at the way we live our lives, Dr. Phil demystifies how your self-concept came to be and gives a nuts-and-bolts approach to creating a new plan for living and, in turn, for discovering the real you. In this groundbreaking work, Dr. Phil challenges you to find your "authentic self" -- that person you once were before life took its toll. It is you at your greatest, most fulfilled, most real moment. It is the person you have always wanted to be, but were too distracted, busy, or scared to become. Instead, you have created a "fictional self" -- taking on the identity of who you believe you are supposed be, the person people tell you you are. The incongruence between these two selves is what leads you to feel that your life is incomplete, unbalanced, and altogether more difficult than it really should be. The good news is it no longer needs to be that way. By using the plan set forth in Self Matters, Dr. Phil helps you to demystify your self-concept and learn how to reclaim your authentic self. In evaluating your life by only the facts, you can learn to think beyond the excuses and fears that have masked the person you have always wanted to be. Self Matters is one of the most forward-thinking works on self-concept and self-esteem ever published. For the first time, an author tells it how it is and, in the process, teaches us all how to live the lives we have always wanted but prevented ourselves from living. We get only one chance in this world, and now, Dr. Phil shows all how to make the most of it.
