Having just completed his masterpiece, The General Theory of Relativity—which provided a brand-new theory of gravity and promised a new perspective on the cosmos as a whole—he set out at once to share his excitement with as wide a public as possible in this popular and accessible book.Here published for the first time as a Penguin Classic, this edition of Relativity features a new introduction by bestselling science author Nigel Calder.

    Would you believe that these five pieces can be reassembled in such a fashion so as to create two apples equal in shape and size to the original? Would you believe that you could make something as large as the sun by breaking a pea into a finite number of pieces and putting it back together again? Neither did Leonard Wapner, author of The Pea and the Sun, when he was first introduced to the Banach-Tarski paradox, which asserts exactly such a notion. Written in an engaging style, The Pea and the Sun catalogues the people, events, and mathematics that contributed to the discovery of Banach and Tarski's magical paradox. Wapner makes one of the most interesting problems of advanced mathematics accessible to the non-mathematician.

    In the four main sections of the book, Stein tells the stories of the mathematical thinkers who discerned some of the most fundamental aspects of our universe. From their successes and failures, delusions, and even duels, the trajectories of their innovations—and their impact on society—are traced in this fascinating narrative. Quantum mechanics, space-time, chaos theory and the workings of complex systems, and the impossibility of a "perfect" democracy are all here. Stein's book is both mind-bending and practical, as he explains the best way for a salesman to plan a trip, examines why any thought you could have is imbedded in the number π , and—perhaps most importantly—answers one of the modern world's toughest questions: why the garage can never get your car repaired on time.Friendly, entertaining, and fun, How Math Explains the World is the first book by one of California's most popular math teachers, a veteran of both "math for poets" and Princeton's Institute for Advanced Studies. And it's perfect for any reader wanting to know how math makes both science and the world tick.

    Harmony is central. There are two key aspects to the visual structure of Islamic design, calligraphy using Arabic script-one of the world's great calligraphic traditions-and abstract ornamentation using a varied but remarkably integrated visual language. This art of pure ornament revolves around two central themes; crystalline geometric patterns, the harmonic and symmetrical subdivision of the plane giving rise to intricately interwoven designs that speak of infinity and the omnipresent center; and idealized plant form, spiraling tendrils, leaves, buds and flowers embodying organic life and rhythm.1. WIDE APPEAL: Anyone interested in science, mathematics, design, architecture, and the natural world.2. AUTHORITATIVE: A compelling blend of scholarship and visual presentation, packs an enormous amount of information into a short space.3. BEAUTIFUL PACKAGE: A bargain at $10.00.

    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!

    Many studies have supported this, proving that life expectancy is 75 to 90 percent due to habits and only 10 to 25 percent due to genetics. This means that someone who is genetically destined to die at age 100 may not live past age 60 because of poor habits and lifestyle choices that cause accelerated aging and premature death. Conversely, a person can live to 100 and be functionally healthy. In this highly anticipated follow-up, Diana Schwarzbein, M.D., goes beyond the diet she introduced in her first book—which literally helped thousands of people lose weight—and offers a personalized anti-aging program for readers to heal their metabolisms and stop advanced aging in its tracks. Weaving in groundbreaking research and provocative case studies—including her own regeneration and that of her clients—she leads readers through a series of eye-opening questionnaires, which identify where they are on their path to either accelerated or healthy aging. Based on readers’ answers, she leads them to the “how-to” sections, which explain, in easy-to-follow and personalized detail, the steps they need to take to restore healthy functioning. For each unique situation, she covers five areas: Nutrition , Hormone Replacement Therapy (if needed), Tapering Off Toxic Chemicals or Avoiding Them Completely , Cross-Training Exercises and Stress Management. The Schwarzbein Principle II is sure to follow the success of the first book and will help people live a more healthful lifestyle by embracing a regeneration process to prevent and reverse accelerated aging.

    In the paper, Wigner observed that the mathematical structure of a physical theory often points the way to further advances in that theory and even to empirical predictions.

    The era covered by this book, 1950 to 1990, was surely one of the golden ages of science as well as the American university.Cherished myths are debunked along the way as Gian-Carlo Rota takes pleasure in portraying, warts and all, some of the great scientific personalities of the period Stanislav Ulam (who, together with Edward Teller, signed the patent application for the hydrogen bomb), Solomon Lefschetz (Chairman in the 50s of the Princeton mathematics department), William Feller (one of the founders of modern probability theory), Jack Schwartz (one of the founders of computer science), and many others.Rota is not afraid of controversy. Some readers may even consider these essays indiscreet. After the publication of the essay "The Pernicious Influence of Mathematics upon Philosophy" (reprinted six times in five languages) the author was blacklisted in analytical philosophy circles. Indiscrete Thoughts should become an instant classic and the subject of debate for decades to come."Read Indiscrete Thoughts for its account of the way we were and what we have become; for its sensible advice and its exuberant rhetoric."--The Mathematical Intelligencer"Learned, thought-provoking, politically incorrect, delighting in paradox, and likely to offend but everywhere readable and entertaining."--The American Mathematical Monthly"It is about mathematicians, the way they think, and the world in which the live. It is 260 pages of Rota calling it like he sees it... Readers are bound to find his observations amusing if not insightful. Gian-Carlo Rota has written the sort of book that few mathematicians could write. What will appeal immediately to anyone with an interest in research mathematics are the stories he tells about the practice of modern mathematics."--MAA Reviews"

    This user-friendly self-study guide is aimed at the general reader who is motivated to tackle that not insignificant challenge. The book is written using straightforward and accessible language, with clear derivations and explanations as well as numerous fully solved problems. For those with minimal mathematical background, the first chapter provides a crash course in foundation mathematics. The reader is then taken gently by the hand and guided through a wide range of fundamental topics, including Newtonian mechanics; the Lorentz transformations; tensor calculus; the Einstein field equations; the Schwarzschild solution (which gives a good approximation of the spacetime of our Solar System); simple black holes and relativistic cosmology. Following the historic 2015 LIGO (Laser Interferometer Gravitational-Wave Observatory) detection, there is now an additional chapter on gravitational waves, ripples in the fabric of spacetime that potentially provide a revolutionary new way to study the universe. Special relativity helps explain a huge range of non-gravitational physical phenomena and has some strangely counter-intuitive consequences. These include time dilation, length contraction, the relativity of simultaneity, mass-energy equivalence and an absolute speed limit. General relativity, the leading theory of gravity, is at the heart of our understanding of cosmology and black holes.Understand even the basics of Einstein's amazing theory and the world will never seem the same again.

    The year 2000 is alternatively the year 2544 (Buddhist), 6236 (Ancient Egyptian), 5761 (Jewish) or simply the Year of the Dragon (Chinese). The story of the creation of the Western calendar, which is related in this book, is a story of emperors and popes, mathematicians and monks, and the growth of scientific calculation to the point where, bizarrely, our measurement of time by atomic pulses is now more accurate than time itself: the Earth is an elderly lady and slightly eccentric - she loses half a second a century. Days have been invented (Julius Caesar needed an extra 80 days in 46BC), lost (Pope Gregory XIII ditched ten days in 1582) and moved (because Julius Caesar had 31 in his month, Augustus determined that he should have the same, so he pinched one from February).
