Devised in India in the 7th and 8th centuries and brought to North Africa by Muslim traders, the Hindu-Arabic system helped transform the West into the dominant force in science, technology, and commerce, leaving behind Muslim cultures which had long known it but had failed to see its potential.The young Italian, Leonardo of Pisa (better known today as Fibonacci), had learned the Hindu number system when he traveled to North Africa with his father, a customs agent. The book he created was Liber abbaci, the "Book of Calculation," and the revolution that followed its publication was enormous. Arithmetic made it possible for ordinary people to buy and sell goods, convert currencies, and keep accurate records of possessions more readily than ever before. Liber abbaci's publication led directly to large-scale international commerce and the scientific revolution of the Renaissance.Yet despite the ubiquity of his discoveries, Leonardo of Pisa remains an enigma. His name is best known today in association with an exercise in Liber abbaci whose solution gives rise to a sequence of numbers--the Fibonacci sequence--used by some to predict the rise and fall of financial markets, and evident in myriad biological structures.One of the great math popularizers of our time, Keith Devlin recreates the life and enduring legacy of an overlooked genius, and in the process makes clear how central numbers and mathematics are to our daily lives.

    I bump along, in fits and starts, on a perpetual path to finding better ways for me and my mate, Anxiety, to get around. It's everything I do.Sarah Wilson—bestselling author and entrepreneur, intrepid solver of problems and investigator of how to live a better life—has helped over 1.2 million people across the world to quit sugar. She has also been an anxiety sufferer her whole life.In her new book, she directs her intense focus and fierce investigatory skills onto this lifetime companion of hers, looking at the triggers and treatments, the fashions and fads. She reads widely and interviews fellow sufferers, mental health experts, philosophers, and even the Dalai Lama, processing all she learns through the prism her own experiences.Sarah pulls at the thread of accepted definitions of anxiety, and unravels the notion that it is a difficult, dangerous disease that must be medicated into submission. Ultimately, she re-frames anxiety as a spiritual quest rather than a burdensome affliction, a state of yearning that will lead us closer to what really matters.Practical and poetic, wise and funny, this is a small book with a big heart. It will encourage the myriad sufferers of the world's most common mental illness to feel not just better about their condition, but delighted by the possibilities it offers for a richer, fuller life.

    Original, well researched, and well documented by distinguished sources, The Field is a book of hope and inspiration for today's world.

    According to church founder Bobby Henderson, the universe and all life within it were created by a mystical and divine being: the Flying Spaghetti Monster. What drives the FSM's devout followers, a.k.a. Pastafarians? Some say it's the assuring touch from the FSM's "noodly appendage." Then there are those who love the worship service, which is conducted in pirate talk and attended by congregants in dashing buccaneer garb. Still others are drawn to the Church's flimsy moral standards, religious holidays every Friday, or the fact that Pastafarian heaven is way cooler: Does your heaven have a Stripper Factory and a Beer Volcano? Intelligent Design has finally met its match—and it has nothing to do with apes or the Olive Garden of Eden.Within these pages, Bobby Henderson outlines the true facts—dispelling such malicious myths as evolution ("only a theory"), science ("only a lot of theories"), and whether we're really descended from apes (fact: Humans share 95 percent of their DNA with chimpanzees, but they share 99.9 percent with pirates!)See what impressively credentialed top scientists have to say:"If Intelligent Design is taught in schools, equal time should be given to the FSM theory and the non-FSM theory."—Professor Douglas Shaw, Ph.D."Do not be hypocritical. Allow equal time for other alternative 'theories' like FSMism, which is by far the tastier choice."—J. Simon, Ph.D."In my scientific opinion, when comparing the two theories, FSM theory seems to be more valid than classic ID theory."—Afshin Beheshti, Ph.D.

    Lisa Sanders, author of the monthly New York Times Magazine column "Diagnosis," the inspiration for the hit Fox TV series House, M.D.The experience of being ill can be like waking up in a foreign country. Life, as you formerly knew it, is on hold while you travel through this other world as unknown as it is unexpected. When I see patients in the hospital or in my office who are suddenly, surprisingly ill, what they really want to know is, ‘What is wrong with me?’ They want a road map that will help them manage their new surroundings. The ability to give this unnerving and unfamiliar place a name, to know it–on some level–restores a measure of control, independent of whether or not that diagnosis comes attached to a cure. Because, even today, a diagnosis is frequently all a good doctor has to offer.A healthy young man suddenly loses his memory–making him unable to remember the events of each passing hour. Two patients diagnosed with Lyme disease improve after antibiotic treatment–only to have their symptoms mysteriously return. A young woman lies dying in the ICU–bleeding, jaundiced, incoherent–and none of her doctors know what is killing her. In Every Patient Tells a Story, Dr. Lisa Sanders takes us bedside to witness the process of solving these and other diagnostic dilemmas, providing a firsthand account of the expertise and intuition that lead a doctor to make the right diagnosis.Never in human history have doctors had the knowledge, the tools, and the skills that they have today to diagnose illness and disease. And yet mistakes are made, diagnoses missed, symptoms or tests misunderstood. In this high-tech world of modern medicine, Sanders shows us that knowledge, while essential, is not sufficient to unravel the complexities of illness. She presents an unflinching look inside the detective story that marks nearly every illness–the diagnosis–revealing the combination of uncertainty and intrigue that doctors face when confronting patients who are sick or dying. Through dramatic stories of patients with baffling symptoms, Sanders portrays the absolute necessity and surprising difficulties of getting the patient’s story, the challenges of the physical exam, the pitfalls of doctor-to-doctor communication, the vagaries of tests, and the near calamity of diagnostic errors. In Every Patient Tells a Story, Dr. Sanders chronicles the real-life drama of doctors solving these difficult medical mysteries that not only illustrate the art and science of diagnosis, but often save the patients’ lives.

    Nor is it a collection of bizarre facts, though the Angel of the Bizarre might well find himself at home in it. It is not a scientific contribution, a vehicle for an exotic teaching, a testament, a document, a fable. It is simply an account - at times figurative, at times factual - of a first excursion into some as yet scarcely explored realms of consciousness. The Morning of the Magicians is a classic of radical literature, a book that has challenged assumptions and conventional knowledge for decades. It has shaken the foundations of beliefs all over the world and may be the most influential book published in the twentieth century. Louis Pauwels and Jacques Bergier spent years searching "through all the regions of consciousness, to the frontiers of science and tradition" and opened their minds to any fact or theory that went beyond the frontier of current theories. The result is this remarkable work, and the stream of possibilities that it contains: Do mutants exist, are they a future form of man? Does extrasensory perception reveal that human consciousness has advanced beyond its currently accepted limits? What connects the ancient art of alchemy and modern atomic physics?

    Just how calculus makes these things possible and in doing so finds a correspondence between real numbers and the real world is the subject of this dazzling book by a writer of extraordinary clarity and stylistic brio. Even as he initiates us into the mysteries of real numbers, functions, and limits, Berlinski explores the furthest implications of his subject, revealing how the calculus reconciles the precision of numbers with the fluidity of the changing universe. "An odd and tantalizing book by a writer who takes immense pleasure in this great mathematical tool, and tries to create it in others."--New York Times Book Review

    But how does virality actually work? In The Rules of Contagion, epidemiologist Adam Kucharski explores topics including gun violence, online manipulation, and, of course, outbreaks of disease to show how much we get wrong about contagion, and how astonishing the real science is.Why did the president retweet a Mussolini quote as his own? Why do financial bubbles take off so quickly? And why are disinformation campaigns so effective? By uncovering the crucial factors driving outbreaks, we can see how things really spread -- and what we can do about it.Whether you are an author seeking an audience, a defender of truth, or simply someone interested in human social behavior, The Rules of Contagion is an essential guide to modern life.
