    Why do people—even identical twins reared in the same home—differ so much in personality? Armed with an inquiring mind and insights from evolutionary psychology, Judith Rich Harris sets out to solve the mystery of human individuality.

    We donate our time and money to charities and causes we deem worthy, choose careers we consider meaningful, and patronize businesses and buy products we believe make the world a better place. Unfortunately, we often base these decisions on assumptions and emotions rather than facts. As a result, even our best intentions often lead to ineffective—and sometimes downright harmful—outcomes. How can we do better? While a researcher at Oxford, trying to figure out which career would allow him to have the greatest impact, William MacAskill confronted this problem head on. He discovered that much of the potential for change was being squandered by lack of information, bad data, and our own prejudice. As an antidote, he and his colleagues developed effective altruism, a practical, data-driven approach that allows each of us to make a tremendous difference regardless of our resources. Effective altruists believe that it’s not enough to simply do good; we must do good better. At the core of this philosophy are five key questions that help guide our altruistic decisions: How many people benefit, and by how much? Is this the most effective thing I can do? Is this area neglected? What would have happened otherwise? What are the chances of success, and how good would success be? By applying these questions to real-life scenarios, MacAskill shows how many of our assumptions about doing good are misguided. For instance, he argues one can potentially save more lives by becoming a plastic surgeon rather than a heart surgeon; measuring overhead costs is an inaccurate gauge of a charity’s effectiveness; and, it generally doesn’t make sense for individuals to donate to disaster relief. MacAskill urges us to think differently, set aside biases, and use evidence and careful reasoning rather than act on impulse. When we do this—when we apply the head and the heart to each of our altruistic endeavors—we find that each of us has the power to do an astonishing amount of good.

    They expect objects to obey principles of physics, and they're startled when things disappear or defy gravity. Yet they can also read emotions and respond with anger, sympathy, and joy. In Descartes' Baby, Bloom draws on a wealth of scientific discoveries to show how these two ways of knowing give rise to such uniquely human traits as humor, disgust, religion, art, and morality. How our dualist perspective, developed throughout our lives, profoundly influences our thoughts, feelings, and actions is the subject of this richly rewarding book.

    The volume has three parts. The studies in the first part examine the history of hermeneutics, its central themes and the outstanding issues it has to confront. In Part II, Ricoeur's own current, constructive position is developed. A concept of the text is formulated as the implications of the theory are pursued into the domains of sociology, psychoanalysis and history. Many of the essays appear here in English for the first time; the editor's introduction brings out their background in Ricoeur's thought and the continuity of his concerns. The volume will be of great importance for those interested in hermeneutics and Ricoeur's contribution to it, and will demonstrate how much his approach offers to a number of disciplines.

    Because the Wright brothers worked in secrecy, word of their first flights had not reached Europe when Santos-Dumont took to the skies in 1906. The dashing, impeccably dressed inventor entertained Paris with his airborne antics--barhopping in a little dirigible that he tied to lampposts, circling above crowds around the Eiffel Tower, and crashing into rooftops. A man celebrated, even pursued by the press in Paris, London, and New York, Santos-Dumont dined regularly with the Cartiers, the Rothschilds, and the Roosevelts. But beneath his lively public exterior, Santos-Dumont was a frenzied genius tortured by the weight of his own creation.Wings of Madness chronicles the science and history of early aviation and offers a fascinating glimpse into the mind of an extraordinary and tormented man, vividly depicting the sights and sounds of turn-of-the-century Paris. It is a book that will do for aviation what The Man Who Loved Only Numbers did for mathematics.

    Within the past ten years, however, mathematicians have proven that they hold the key to unlocking the mysteries of our world--and ourselves. In The Mathematics of Life, Ian Stewart provides a fascinating overview of the vital but little-recognized role mathematics has played in pulling back the curtain on the hidden complexities of the natural world--and how its contribution will be even more vital in the years ahead. In his characteristically clear and entertaining fashion, Stewart explains how mathematicians and biologists have come to work together on some of the most difficult scientific problems that the human race has ever tackled, including the nature and origin of life itself.

    Their quest: to be the first to detect gravitational waves, infinitesimal quakes that stretch and compress space-time and could add a brand-new dimension to our universal knowledge-allowing us to hear a sun going supernova, black holes colliding, and perhaps one day, the remnant rumble of the Big Bang itself...

    Travel back to ancient Greece with Professor Emeritus of Philosophy Donald R. Moor and author Robert M. Pirsig ("Zen and the Art of Motorcycle Maintenance") to meet this legendary thinker. In addition to expanding upon his famous allegory of the cave, Plato talks about learning through dialogue, the primacy of good and the price of wrong doing, democracy, freedom and censorship, women's equality, love, and mathematics, and the search for truth.

    This question is central to all the great religions, Kreeft demonstrates, for striving toward holiness, moving toward perfect love, is the whole purpose of life.Kreeft admits that he is only a beginner on the climb to holiness, and it is to novices like him that he has written this engaging and encouraging book. Using the insights and experiences of saints and great spiritual writers throughout history, Kreeft shows what holiness is and how it can be achieved. He especially draws upon the spiritual classic Abandonment to Divine Providence by Jean-Pierre de Caussade, S.J. The core of Caussade's timeless gem is that God reveals himself to all of us through the daily events of our lives. The surest way toward spiritual growth, therefore, is by perceiving and accepting the merciful will of God in every situation.Kreeft stresses the simplicity of his approach to holiness, which focuses mainly on the virtue of love. Sanctity is love, he asserts, and only that can give us what we all long for—deep and lasting joy.

    To truly flourish, the human spirit needs to be present in its surroundings and attuned to the Now. It needs to act on what it knows is possible and to experience how the smallest actions can have massive consequences. This is the reality of the Prophet’s Way, a path--both literal and figurative--that the author walked with his spiritual mentor Herr Müller that skirts the edge of the precipice, where one can experience a truly spontaneous life under seemingly overwhelming and impossible circumstances.In The Prophet’s Way, Thom Hartmann shares his intense spiritual journey, a story that melds recent discoveries in science with ancient truths. Through insightful and engaging vignettes Hartmann teaches that accepting the challenge to have faith means living on the edge--remaining in the moment--because it is here where the material and spiritual worlds meet. He offers readers a unique view into his experiences of expanded consciousness, providing a powerful example of how we can re-create our future by reconnecting to the sacred heartbeat of the world.

    At a Chinese restaurant outside of Philadelphia, a father asks his fifteen-year-old daughter a deceptively simple question: "How would you define nothing?" With that, the girl who once tried to fail geometry as a conscientious objector starts reading up on general relativity and quantum mechanics, as she and her dad embark on a life-altering quest for the answers to the universe's greatest mysteries.Before Amanda Gefter became an accomplished science writer, she was a twenty-one-year-old magazine assistant willing to sneak her and her father, Warren, into a conference devoted to their physics hero, John Wheeler. Posing as journalists, Amanda and Warren met Wheeler, who offered them cryptic clues to the nature of reality: The universe is a self-excited circuit, he said. And, The boundary of a boundary is zero. Baffled, Amanda and Warren vowed to decode the phrases--and with them, the enigmas of existence. When we solve all that, they agreed, we'll write a book.Trespassing on Einstein's Lawn is that book, a memoir of the impassioned hunt that takes Amanda and her father from New York to London to Los Alamos. Along the way, they bump up against quirky science and even quirkier personalities, including Leonard Susskind, the former Bronx plumber who invented string theory; Ed Witten, the soft-spoken genius who coined the enigmatic M-theory; even Stephen Hawking.What they discover is extraordinary: the beginnings of a monumental paradigm shift in cosmology, from a single universe we all share to a splintered reality in which each observer has her own. Reality, the Gefters learn, is radically observer-dependent, far beyond anything of which Einstein or the founders of quantum mechanics ever dreamed--with shattering consequences for our understanding of the universe's origin. And somehow it all ties back to that conversation, to that Chinese restaurant, and to the true meaning of nothing.Throughout their journey, Amanda struggles to make sense of her own life--as her journalism career transforms from illusion to reality, as she searches for her voice as a writer, as she steps from a universe shared with her father to at last carve out one of her own. It's a paradigm shift you might call growing up.By turns hilarious, moving, irreverent, and profound, Trespassing on Einstein's Lawn weaves together story and science in remarkable ways. By the end, you will never look at the universe the same way again.Praise for Trespassing on Einstein's Lawn"Nothing quite prepared me for this book. Wow. Reading it, I alternated between depression--how could the rest of us science writers ever match this?--and exhilaration."--Scientific American "To Do: Read Trespassing on Einstein's Lawn. Reality doesn't have to bite."--New York "A zany superposition of genres . . . It's at once a coming-of-age chronicle and a father-daughter road trip to the far reaches of this universe and 10,500 others."--The Philadelphia Inquirer

    Using the data they are constantly collecting about where we travel, where we shop, what we buy, and what interests us, they can begin to predict our daily habits, and increasingly we are relinquishing our decision-making to algorithms. Are we giving this up too easily?Without understanding what mathematics can and can't do it is impossible to get a handle on how it is changing our lives. Outnumbered is a journey to the dark side of mathematics, from how it dictates our social media activities to our travel routes. David Sumpter investigates whether mathematics is crossing dangerous lines when it comes to what we can make decisions about.This book will show how math impacts all parts of our lives: from the algorithms that decide whom we interact with to the statistical methods that categorize us as potential criminals. It tests financial algorithms that purport to generate money from nothing, and reveals that we are constantly manipulated by the math used by others, from algorithms choosing the news we hear to automated hospital waiting lists deciding whether we receive treatment.Using interviews with those people working at the cutting edge of mathematical and data research, Outnumbered will explain how math and stats work in the real world, and what we should and shouldn't worry about.

    Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria. Worse, these "too good to not be true" theories are actually untestable and they have left the field in a cul-de-sac. To escape, physicists must rethink their methods. Only by embracing reality as it is can science discover the truth.

    It resurrects from the vaults of neglect the polymath Jerome Cardano, a Milanese of the sixteenth century. Who is he? A gambler and blasphemer, inventor and chancer, plagued by demons and anxieties, astrologer to kings, emperors and popes. This stubborn and unworldly man was the son of a lawyer and a brothel keeper, but also a gifted physician and the unacknowledged discoverer of the mathematical foundations of quantum physics. That is the argument of this charming and intoxicatingly clever book, which is truly original in its style, and in the manner of the modernists embodies in its very form its theories about the world.'The Quantum Astrologer’s Handbook' is a science book with the panache of a novel, for readers of Carlo Rovelli or Umberto Eco. It is a work of and about genius.
