A roadmap through the intricacies of public documents and online databases, the book also highlights genetic testing resources that can make it possible to know one's distant tribal roots in Africa.For Oprah, the path back to the past was emotion-filled and profoundly illuminating, connecting the narrative of her family to the larger American narrative and "anchoring" her in a way not previously possible. For the reader, Finding Oprah's Roots offers the possibility of an equally rewarding experience.

         Ronan O'Gara has been at the heart of Munster and Irish rugby for the past fifteen years. Now, as he comes to the end of a glittering playing career, it is time for him to reflect on those many successes and occasional failures with the straight-talking attitude that has become his trademark. Never one to shy away from the truth, the result is Ronan O'Gara: Unguarded.     Packed full of anecdotes and analysis of the teammates O'Gara has been proud to share the shirt with, and of the coaches he has played under -- often in controversial circumstances -- this is the definitive record of an era when Munster rose to triumph in Europe, and Ireland to win the Grand Slam, before crashing down to earth again. It is simply the must-have rugby book of the year.

    It provides a transition from elementary calculus to advanced courses in real and complex function theory and introduces the reader to some of the abstract thinking that pervades modern analysis.

    The First seven chapters deal with structure related aspects such as lattice and crystal structures, bonding, packing and diffusion of atoms followed by imperfections and lattice vibrations. Chapter eight deals mainly with experimental methods of determining structures of given materials. While the next nine chapters cover various physical properties of crystalline solids, the last chapter deals with the anisotropic properties of materials. This chapter has been added for benefit of readers to understand the crystal properties (anisotropic) in terms of some simple mathematical formulations such as tensor and matrix. New to the Second Edition: Chapter on: *Anisotropic Properties of Materials

    This edition, which was prepared by Kip S. Thorne (Feynman Professor of Theoretical Physics at California Institute of Technology), fully incorporates all the errata and corrections gathered (but never used in a published edition) by Feynman.

    As we enter the year 2000, zero is once again making its presence felt. Nothing itself, it makes possible a myriad of calculations. Indeed, without zero mathematicsas we know it would not exist. And without mathematics our understanding of the universe would be vastly impoverished. But where did this nothing, this hollow circle, come from? Who created it? And what, exactly, does it mean? Robert Kaplan's The Nothing That Is: A Natural History of Zero begins as a mystery story, taking us back to Sumerian times, and then to Greece and India, piecing together the way the idea of a symbol for nothing evolved. Kaplan shows us just how handicapped our ancestors were in trying to figurelarge sums without the aid of the zero. (Try multiplying CLXIV by XXIV). Remarkably, even the Greeks, mathematically brilliant as they were, didn't have a zero--or did they? We follow the trail to the East where, a millennium or two ago, Indian mathematicians took another crucial step. By treatingzero for the first time like any other number, instead of a unique symbol, they allowed huge new leaps forward in computation, and also in our understanding of how mathematics itself works. In the Middle Ages, this mathematical knowledge swept across western Europe via Arab traders. At first it was called dangerous Saracen magic and considered the Devil's work, but it wasn't long before merchants and bankers saw how handy this magic was, and used it to develop tools likedouble-entry bookkeeping. Zero quickly became an essential part of increasingly sophisticated equations, and with the invention of calculus, one could say it was a linchpin of the scientific revolution. And now even deeper layers of this thing that is nothing are coming to light: our computers speakonly in zeros and ones, and modern mathematics shows that zero alone can be made to generate everything.Robert Kaplan serves up all this history with immense zest and humor; his writing is full of anecdotes and asides, and quotations from Shakespeare to Wallace Stevens extend the book's context far beyond the scope of scientific specialists. For Kaplan, the history of zero is a lens for looking notonly into the evolution of mathematics but into very nature of human thought. He points out how the history of mathematics is a process of recursive abstraction: how once a symbol is created to represent an idea, that symbol itself gives rise to new operations that in turn lead to new ideas. Thebeauty of mathematics is that even though we invent it, we seem to be discovering something that already exists.The joy of that discovery shines from Kaplan's pages, as he ranges from Archimedes to Einstein, making fascinating connections between mathematical insights from every age and culture. A tour de force of science history, The Nothing That Is takes us through the hollow circle that leads to infinity.

    Calculus is not a prerequisite, although examples and exercises using very basic calculus are included (labeled Calculus Required.) The most technology-friendly text on the market, Introductory Linear Algebra is also the most flexible. By omitting certain sections, instructors can cover the essentials of linear algebra (including eigenvalues and eigenvectors), to show how the computer is used, and to introduce applications of linear algebra in a one-semester course.

    Captain Shore’s enthusiasm for firearms and especially for rifles led him to take every possible opportunity to try out different weapons, ammunition and methods of shooting. His interest was combined with sound common sense, and he would never countenance a rumour about a particular weapon or incident unless he was able to confirm it for himself.As a result everything in this book is based on his personal experience. In World War II Captain Shore took part in the British landings at D-Day, and fought in Normandy and northern Europe. He came across many different weapons in varying condition, some of the worst being those used by the Dutch and Belgian resistance fighters. He was keen to learn from experienced snipers and then to train others, and he became an officer sniping instructor at the British Army of the Rhine Training Centre.He shares a wealth of first-hand knowledge of different rifles, pistols, machine guns, ammunition, telescopes, binoculars and all the equipment a sniper should carry. This is not only an account of sniping in World War II but also a guide to all aspects of sniping based on personal knowledge and experience in training and battle. Illustrated heavily with photos, pictures and other illustrations of snipers, their weapons and their tactics.
