Gold Dust Woman gives "the gold standard of rock biographers" (The Boston Globe) his ideal topic: Nicks' work and life are equally sexy and interesting, and Davis delves deeply into each, unearthing fresh details from new, intimate interviews and interpreting them to present a rich new portrait of the star. Just as Nicks (and Lindsay Buckingham) gave Fleetwood Mac the "shot of adrenaline" they needed to become real rock stars—according to Christine McVie—Gold Dust Woman is vibrant with stories and with a life lived large and hard:

—How Nicks and Buckingham were asked to join Fleetwood Mac and how they turned the band into stars

—The affairs that informed Nicks' greatest songs

—Her relationships with the Eagles' Don Henley and Joe Walsh, and with Fleetwood himself

—Why Nicks married her best friend's widower

—Her dependency on cocaine, drinking and pot, but how it was a decade-long addiction to Klonopin that almost killed her

— Nicks’ successful solo career that has her still performing in venues like Madison Square Garden

—The cult of Nicks and its extension to chart-toppers like Taylor Swift and the Dixie Chicks

This major survey of mathematics, featuring the work of 18 outstanding Russian mathematicians and including material on both elementary and advanced levels, encompasses 20 prime subject areas in mathematics in terms of their simple origins and their subsequent sophisticated developement. As Professor Morris Kline of New York University noted, "This unique work presents the amazing panorama of mathematics proper. It is the best answer in print to what mathematics contains both on the elementary and advanced levels."

Beginning with an overview and analysis of mathematics, the first of three major divisions of the book progresses to an exploration of analytic geometry, algebra, and ordinary differential equations. The second part introduces partial differential equations, along with theories of curves and surfaces, the calculus of variations, and functions of a complex variable. It furthur examines prime numbers, the theory of probability, approximations, and the role of computers in mathematics. The theory of functions of a real variable opens the final section, followed by discussions of linear algebra and nonEuclidian geometry, topology, functional analysis, and groups and other algebraic systems.

Thorough, coherent explanations of each topic are further augumented by numerous illustrative figures, and every chapter concludes with a suggested reading list. Formerly issued as a three-volume set, this mathematical masterpiece is now available in a convenient and modestly priced one-volume edition, perfect for study or reference.

"This is a masterful English translation of a stupendous and formidable mathematical masterpiece . . ." — Social Science

From the bestselling author of Hammer of the Gods comes the complete story of Guns N? Roses ? from their drug-fueled blastoff in the 80s to the turbulent life of legendary singer Axl Rose, and his fifteen-year, multimillion dollar quest to make the perfect hard rock album.

Riotous world tours. Drug-induced rampages. One hundred millions albums sold. In his sixth major rock biography, Stephen Davis details the riveting story of the last great rock band. Watch You Bleed documents the life of every band member, including the improbable story of W. Axl Rose. Davis brilliantly captures the Guns? raw power ? from the gutters of Sunset Strip to the biggest stadiums on the planet. Based on exclusive interviews, private archives, and packed with stunning revelations, Watch You Bleed is the savage, definitive, and highly unauthorized story of Guns N? Roses. For the first time, millions of fans will learn the whole truth about this legendary band.

In Jim Morrison, critically acclaimed journalist Stephen Davis, author of Hammer of the Gods, unmasks Morrison’s constructed personas of the Lizard King and Mr. Mojo Risin’ to reveal a man of fierce intelligence whose own destructive tendencies both fueled his creative ambitions and brought about his downfall. Gathered from dozens of original interviews and investigations of Morrison’s personal journals, Davis has assembled a vivid portrait of a misunderstood genius, tracing the arc of Morrison’s life from his troubled youth to his international stardom, when his drug and alcohol binges, tumultuous sexual affairs, and fractious personal relationships reached a frenzied peak. For the first time, Davis is able to reconstruct Morrison’s last days in Paris to solve one of the greatest mysteries in music history in a shocking final chapter.

Compelling and harrowing, intimate and revelatory, Jim Morrison is the definitive biography of the rock idol in snakeskin and leather who defined the 1960s.

As a young music journalist in 1975, Stephen Davis got the opportunity of a lifetime: an invitation to cover the sold-out 1975 North American tour of Led Zeppelin, the biggest and most secretive rock band in the world, for a national magazine. He received a backstage pass, was granted interviews with band members, and even got a prized seat on the band's luxurious tour jet, The Starship. While on duty, he chronicled the Zeppelin tour in three notebooks, but after writing his article in 1975 he misplaced them. After three decades of searching, in 2005 he finally found the notebooks, on the covers of which he had scribbled the words "LZ-'75," and unearthed an amazing amount of new information from the tour including:

• Lost interviews with canny vocalist Robert Plant and the brilliant guitarist Jimmy Page

• Information on the rock icon who moonlighted as a heroin dealer

• Revelations about the identity of the lover about whom Robert Plant sings in "What Is and What Should Never Be" and "Black Country Woman"

• A detailed chronicle of each performance from a musical perspective, and a vivid account of the band members' extravagant, and often troubled, lives on tour

Tied together by Davis's entertaining narrative, and including more than forty never-before-published photographs, LZ-'75 is an unprecedented and comprehensive personal portrait of the greatest (and most notoriously press-shy) rock band in history at its apex.

The saga of the Rolling Stones is the central epic in rock mythology. From their debut as the intermission band at London’s Marquee Club in 1962 through their latest record—setting Bridges to Babylon world tour, the Rolling Stones have defined a musical genre and experienced godlike adulation, quarrels, addiction, legal traumas, and descents into madness and death_while steadfastly refusing to fade away. Now Stephen Davis, the New York Times bestselling author of Hammer of the Gods and Walk This Way, who has followed the Stones for three decades, presents their whole story, replete with vivid details of the Stones’ musical successes_and personal excesses.

Born into the wartime England of air-raid sirens, bombing raids, and strict rationing, the Rolling Stones came of age in the 1950s, as American blues and pop arrived in Europe. Among London’s most ardent blues fans in the early 1960s was a short blond teenage guitar player named Brian Jones, who hooked up with a lorry driver’s only son, Charlie Watts, a jazz drummer. At the same time, popular and studious Michael Philip Jagger–who, as a boy, bawled out a phonetic version of “La Bamba” with an eye-popping intensity that scared his parents–began sharing blues records with a primary school classmate, Keith “Ricky” Richards, a shy underachiever, whose idol was Chuck Berry. In 1962 the four young men, joined by Bill Perks (later Wyman) on bass, formed a band rhythm and blues band, which Brian Jones named the “the Rollin’ Stones” in honor of the Muddy Waters blues classic.

Using the biography of the Rolling Stones as a narrative spine, Old God Almost Dead builds a new, multilayered version of the Stones’ story, locating the band beyond the musical world they dominated and showing how they influenced, and were influenced by, the other artistic movements of their era: the blues revival, Swinging London, the Beats, Bob Dylan’s Stones-inspired shift from protest to pop, Pop Art and Andy Warhol’s New York, the “Underground” politics of the 1960s, Moroccan energy and European orientalism, Jamaican reggae, the Glam and Punk subcultures, and the technologic advances of the video and digital revolution. At the same time, Old Gods Almost Dead documents the intense backstage lives of the Stones: the feuds, the drugs, the marriages, and the affairs that inspired and informed their songs; and the business of making records and putting on shows.

The first new biography of the Rolling Stones since the early 1980s, Old Gods Almost Dead is the most comprehensive book to date, and one of the few to cover all the band’s members. Illustrated throughout with photos of pivotal moments, it is a celebration of the Rolling Stones as an often courageous, often foolish gang of artists who not only showed us new worlds, but new ways of living in them. It is a saga as raunchily, vibrantly entertaining as the Stones themselves.

"The main object of this book is to dispel the fear of mathematics," declares author W. W. Sawyer, adding that "Many people regard mathematicians as a race apart, possessed of almost supernatural powers. While this is very flattering for successful mathematicians, it is very bad for those who, for one reason or another, are attempting to learn the subject." Now retired, Sawyer won international renown for his innovative teaching methods, which he used at colleges in England and Scotland as well as Africa, New Zealand, and North America. His insights into the pleasures and practicalities of mathematics will appeal to readers of all backgrounds.

Carly Simon has won two Grammys and an Academy Award, and her albums have sold more than forty million copies. Her music has touched countless lives since her debut in the 1970s, yet her own life story has remained unpublished-until now. Tapping private archives, family interviews, and a forty-year friendship with the legend herself, Stephen Davis at last captures Carly Simon's extraordinary journey from shy teenager to superstar. More Room in a Broken Heart candidly covers everything her fans want to know, including:

Growing up with her father, publishing mogul Richard Simon The Bob Dylan turning point that launched her career The real story behind "You're So Vain" Carly's severe stage fright (she's the only musical guest to pretape an SNL segment) Romantic involvements with Mick Jagger, Warren Beatty, and Cat Stevens How Carly and James Taylor went from being pop music's reigning couple to independent souls living at opposite ends of Massachusetts Surviving breast cancer Her recent financial and spiritual crisesAlong the way, Davis vividly takes readers back to some of the most powerful eras in American music history and delivers a tribute worthy of the artist and her loyal fans, who know that nobody does it better than Carly Simon.

What's the best diet for overall health and weight management? How can we change our finances to retire earlier? How can we maximize our chances of finding our soul mate?

In The Calculus of Happiness, Oscar Fernandez shows us that math yields powerful insights into health, wealth, and love. Using only high-school-level math (precalculus with a dash of calculus), Fernandez guides us through several of the surprising results, including an easy rule of thumb for choosing foods that lower our risk for developing diabetes (and that help us lose weight too), simple "all-weather" investment portfolios with great returns, and math-backed strategies for achieving financial independence and searching for our soul mate. Moreover, the important formulas are linked to a dozen free online interactive calculators on the book’s website, allowing one to personalize the equations.

Fernandez uses everyday experiences—such as visiting a coffee shop—to provide context for his mathematical insights, making the math discussed more accessible, real-world, and relevant to our daily lives. Every chapter ends with a summary of essential lessons and takeaways, and for advanced math fans, Fernandez includes the mathematical derivations in the appendices.

A nutrition, personal finance, and relationship how-to guide all in one, The Calculus of Happiness invites you to discover how empowering mathematics can be.

The first part explores functions of one variable, including numbers and sequences, continuous functions, differentiable functions, integration, and sequences and series of functions. The second part examines functions of several variables: the space of several variables and continuous functions, differentiation, multiple integrals, and line and surface integrals, concluding with a selection of related topics. Complete solutions to the problems appear at the end of the text.

Joe Johnston lost Atlanta and John Bell Hood has gotten a bum rap, Stephen Davis argues in his new book, Atlanta Will Fall: Sherman, Joe Johnston, and the Yankee Heavy Battalions. The fall of the city was inevitable because Johnston pursued a strategy that was typical of his career: he fell back. Again and again. To the point where he allowed Sherman's army to within five miles of the city. Against a weaker opponent, Johnston's strategy might have succeeded. But Sherman commanded superior numbers, and he was a bold, imaginative strategist who pressed the enemy daily and used his artillery to pound their lines. Against this combination, Johnston didn't have a chance. And by the time Hood took over the Confederate command, neither did he.

Atlanta Will Fall provides a lively, fast-paced overview of the entire Atlanta campaign from Dalton to Jonesboro. Davis describes the battles and analyzes the strategies. He evaluates the three generals, examining their plans of action, their tactics, and their leadership ability. In doing so, he challenges the commonly held perceptions of the two Confederate leaders and provides a new perspective on one of the most decisive battles of the Civil War.

An excellent supplemental text for courses on the Civil War and American nineteenth-century history, Atlanta Will Fall will engage students with its brisk, concise examination of the fight for Atlanta.

But while the importance of the calculus and mathematical analysis ― the core of modern mathematics ― cannot be overemphasized, the value of this first comprehensive critical history of the calculus goes far beyond the subject matter. This book will fully counteract the impression of laymen, and of many mathematicians, that the great achievements of mathematics were formulated from the beginning in final form. It will give readers a sense of mathematics not as a technique, but as a habit of mind, and serve to bridge the gap between the sciences and the humanities. It will also make abundantly clear the modern understanding of mathematics by showing in detail how the concepts of the calculus gradually changed from the Greek view of the reality and immanence of mathematics to the revised concept of mathematical rigor developed by the great 19th century mathematicians, which held that any premises were valid so long as they were consistent with one another. It will make clear the ideas contributed by Zeno, Plato, Pythagoras, Eudoxus, the Arabic and Scholastic mathematicians, Newton, Leibnitz, Taylor, Descartes, Euler, Lagrange, Cantor, Weierstrass, and many others in the long passage from the Greek "method of exhaustion" and Zeno's paradoxes to the modern concept of the limit independent of sense experience; and illuminate not only the methods of mathematical discovery, but the foundations of mathematical thought as well.

Michael Tagleva is the eldest son and heir to one of the wealthiest banking families in Europe. When visiting Germany he is welcomed as a distinguished guest by the Nazis, but not everything is as it seems and Michael soon finds himself in a labyrinth of deceit and double-cross that spreads from Berlin to Paris and London and intended to destroy his family and lose the British Empire the war.

In this thrilling sequel to Davis’ book, The Tsar’s Banker, his research exposes the details of the story that, after nearly eighty years, the British authorities still classify TOP SECRET. p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Helvetica; color: #878787}

The second edition preserves the book’s clear and concise style, illuminating discussions, and simple, well-motivated proofs. New topics include material on the irrationality of pi, the Baire category theorem, Newton's method and the secant method, and continuous nowhere-differentiable functions.

Review from the first edition:

"This book is intended for the student who has a good, but naïve, understanding of elementary calculus and now wishes to gain a thorough understanding of a few basic concepts in analysis.... The author has tried to write in an informal but precise style, stressing motivation and methods of proof, and ... has succeeded admirably."

—MATHEMATICAL REVIEWS

Not to fear--Idiot's Guides: Calculus I is a curriculum-based companion book created with this audience in mind. This new edition continues the tradition of taking the sting out of calculus by adding more explanatory graphs and illustrations and doubling the number of practice problems! By the time readers are finished, they will have a solid understanding (maybe even a newfound appreciation) for this useful form of math. And with any luck, they may even be able to make sense of their textbooks and teachers.

This new edition is extensively revised and updated with a refocused layout. In addition to the inclusion of extra exercises, the quality and focus of the exercises in this book has improved, which will help motivate the reader. New features include a discussion of infinite products, and expanded sections on metric spaces, the Baire category theorem, multi-variable functions, and the Gamma function.

Reviews from the first edition:

"This is a dangerous book. Understanding Analysis is so well-written and the development of the theory so well-motivated that exposing students to it could well lead them to expect such excellence in all their textbooks. ... Understanding Analysis is perfectly titled; if your students read it that’s what’s going to happen. This terrific book will become the text of choice for the single-variable introductory analysis course; take a look at it next time you’re preparing that class."

-Steve Kennedy, The Mathematical Association of America, 2001

"Each chapter begins with a discussion section and ends with an epilogue. The discussion serves to motivate the content of the chapter while the epilogue points tantalisingly to more advanced topics. ... I wish I had written this book! The development of the subject follows the tried-and-true path, but the presentation is engaging and challenging. Abbott focuses attention immediately on the topics which make analysis fascinating ... and makes them accessible to an inexperienced audience."

-Scott Sciffer, The Australian Mathematical Society Gazette, 29:3, 2002

“One of the most insightful and intelligent rock bios in recent memory.” —Entertainment Weekly

The Band, who backed Bob Dylan when he went electric in 1965 and then turned out a half-dozen albums of beautifully crafted, image-rich songs, is now regarded as one of the most influential rock groups of the '60s. But while their music evoked a Southern mythology, only their Arkansawyer drummer, Levon Helm, was the genuine article. From the cotton fields to Woodstock, from seeing Sonny Boy Williamson and Elvis Presley to playing for President Clinton, This Wheel’s on Fire replays the tumultuous history of our times in Levon’s own unforgettable folksy drawl. This edition is expanded with a new epilogue covering the last dozen years of Levon's life.

Levon Helm (1940-2012) met Ronnie Hawkins at the age of 17 and formed what would soon become The Band. He maintained a successful career as a singer and actor until his death. Stephen Davis is the author of Hammer of the Gods: The Led Zeppelin Saga; More Room in a Broken Heart: The True Adventures of Carly Simon; Old Gods Almost Dead: The 40-Year Odyssey of the Rolling Stones; Jim Morrison: Life, Death, Legend; Walk This Way: The Autobiography of Aerosmith; and others.

The reader who merely wishes to become familiar with the most basic concepts and methods of the calculus of variations need only study the first chapter. Students wishing a more extensive treatment, however, will find the first six chapters comprise a complete university-level course in the subject, including the theory of fields and sufficient conditions for weak and strong extrema. Chapter 7 considers the application of variational methods to the study of systems with infinite degrees of freedom, and Chapter 8 deals with direct methods in the calculus of variations. The problems following each chapter were made specially for this English-language edition, and many of them comment further on corresponding parts of the text. Two appendices and suggestions for supplementary reading round out the text.

Substantially revised and corrected by the translator, this inexpensive new edition will be welcomed by advanced undergraduate and graduate students of mathematics and physics.

The author first applies the necessary mathematical background, including sets, inequalities, absolute value, mathematical induction, and other "precalculus" material. Chapter Two begins the actual study of differential calculus with a discussion of the key concept of function, and a thorough treatment of derivatives and limits. In Chapter Three differentiation is used as a tool; among the topics covered here are velocity, continuous and differentiable functions, the indefinite integral, local extrema, and concrete optimization problems. Chapter Four treats integral calculus, employing the standard definition of the Riemann integral, and deals with the mean value theorem for integrals, the main techniques of integration, and improper integrals. Chapter Five offers a brief introduction to differential equations and their applications, including problems of growth, decay, and motion. The final chapter is devoted to the differential calculus of functions of several variables.

Numerous problems and answers, and a newly added section of "Supplementary Hints and Answers," enable the student to test his grasp of the material before going on. Concise and well written, this text is ideal as a primary text or as a refresher for anyone wishing to review the fundamentals of this crucial discipline.
