    Griffin), Dick Couch's explosive novel poses the chilling and timely question: How safe are America's waterways from terrorist threat?Riding quietly at her moorings on Puget Sound, the U.S. Navy's deadly weapon -- the Trident submarine -- waits for her return to the sea. But an Arab terrorist known as the Shadow has targeted the USS "Michigan," with nearly three hundred nuclear warheads nestled in its missile silos. He intends to take the deadliest weapon of the Cold War and turn it into the deadliest dirty bomb conceivable -- by hijacking the "Spokane," flagship of the nation's largest ferry fleet. The nation, caught by surprise, sends a select team of Navy SEALs to stop the Shadow. They are aided by a savvy FBI agent and the ferry's captain, Ross Peck. Unless the U.S. wields its political might to support his terrorist brothers in the Middle East, the Shadow will unleash a radiological holocaust, and a nightmare beyond imagining. . . .

    The Clay Mathematics Institute is offering a prize of $1 million to anyone who can discover a general solution to the problem. In this book, Avner Ash and Robert Gross guide readers through the mathematics they need to understand this captivating problem.The key to the conjecture lies in elliptic curves, which are cubic equations in two variables. These equations may appear simple, yet they arise from some very deep--and often very mystifying--mathematical ideas. Using only basic algebra and calculus while presenting numerous eye-opening examples, Ash and Gross make these ideas accessible to general readers, and in the process venture to the very frontiers of modern mathematics. Along the way, they give an informative and entertaining introduction to some of the most profound discoveries of the last three centuries in algebraic geometry, abstract algebra, and number theory. They demonstrate how mathematics grows more abstract to tackle ever more challenging problems, and how each new generation of mathematicians builds on the accomplishments of those who preceded them. Ash and Gross fully explain how the Birch and Swinnerton-Dyer Conjecture sheds light on the number theory of elliptic curves, and how it provides a beautiful and startling connection between two very different objects arising from an elliptic curve, one based on calculus, the other on algebra.

    Hungarian-born Erdős believed that the meaning of life was to prove and conjecture. His work in the United States and all over the world has earned him the titles of the century's leading number theorist and the most prolific mathematician who ever lived. Erdős's important work has proved pivotal to the development of computer science, and his unique personality makes him an unforgettable character in the world of mathematics. Incapable of the smallest of household tasks and having no permanent home or job, he was sustained by the generosity of colleagues and by his own belief in the beauty of numbers. Witty and filled with the sort of mathematical puzzles that intrigued Erdős and continue to fascinate mathematicians today, My Brain Is Open is the story of this strange genius and a journey in his footsteps through the world of mathematics, where universal truths await discovery like hidden treasures and where brilliant proofs are poetry.

    The truth is that modern life is extremely stressful; there are many demands on your time and never enough hours in the day. However, being at the end of your tether, worn out and overwhelmed is not the same as having a mental disorder. In fact mental health covers a wide range of illnesses including those which most people are aware of, such as Schizophrenia (which is classed as a psychotic disorder). What you may not be aware of is the number of people who have personality disorders and the reasons for these disorders. Most people are not diagnosed until into their twenties and symptoms will naturally reduce in their forties or fifties. Knowing the difference between the various mental illnesses is essential to ensure you know when a friend or loved one needs professional help as opposed to just your care and attention. This book will guide you through the differences between personality disorders, mental disorders and psychotic disorders. It will help you to understand the different elements of a personality and how you can test your friends to find out which personality type they are. It will even enlighten you as to the basic traits of each of the sixteen personality types, according to the Myers Briggs Personality test. Reading this book will enlighten you as to the names and details of the nine main personality disorders, how to recognize the symptoms of each of these disorders and the best way to treat them. It is important to use this book as a guide to understanding these illnesses and to learn the best way to help and support anyone you know who is suffering from a personality disorder. However, a diagnosis must always be confirmed by a medical professional who will ensure treatment is available. Many people who have a mental health issue will not recognise the issue in themselves; this book will ensure you understand each condition and can help your loved one to get the appropriate treatment. Everyone deserves the chance to have a happy, fulfilling and balanced life. Read this and help those around you have that chance!

    His illuminating explanation is addressed to the person who wants to understand the place of mathematics in modern civilization but who has been intimidated by its supposed difficulty. Mathematics is the language of size, shape, and order—a language Hogben shows one can both master and enjoy.

    In A Brief History of Mathematical Thought, Luke Heaton explores how the language of mathematics has evolved over time, enabling new technologies and shaping the way people think. From stone-age rituals to algebra, calculus, and the concept of computation, Heaton shows the enormous influence of mathematics on science, philosophy and the broader human story. The book traces the fascinating history of mathematical practice, focusing on the impact of key conceptual innovations. Its structure of thirteen chapters split between four sections is dictated by a combination of historical and thematic considerations. In the first section, Heaton illuminates the fundamental concept of number. He begins with a speculative and rhetorical account of prehistoric rituals, before describing the practice of mathematics in Ancient Egypt, Babylon and Greece. He then examines the relationship between counting and the continuum of measurement, and explains how the rise of algebra has dramatically transformed our world. In the second section, he explores the origins of calculus and the conceptual shift that accompanied the birth of non-Euclidean geometries. In the third section, he examines the concept of the infinite and the fundamentals of formal logic. Finally, in section four, he considers the limits of formal proof, and the critical role of mathematics in our ongoing attempts to comprehend the world around us. The story of mathematics is fascinating in its own right, but Heaton does more than simply outline a history of mathematical ideas. More importantly, he shows clearly how the history and philosophy of maths provides an invaluable perspective on human nature.
