We often overlook the historical link between mathematics and technological advances, says Stewart—but this connection is integral to any complete understanding of human history.Equations are modeled on the patterns we find in the world around us, says Stewart, and it is through equations that we are able to make sense of, and in turn influence, our world. Stewart locates the origins of each equation he presents—from Pythagoras's Theorem to Newton's Law of Gravity to Einstein's Theory of Relativity—within a particular historical moment, elucidating the development of mathematical and philosophical thought necessary for each equation's discovery. None of these equations emerged in a vacuum, Stewart shows; each drew, in some way, on past equations and the thinking of the day. In turn, all of these equations paved the way for major developments in mathematics, science, philosophy, and technology. Without logarithms (invented in the early 17th century by John Napier and improved by Henry Briggs), scientists would not have been able to calculate the movement of the planets, and mathematicians would not have been able to develop fractal geometry. The Wave Equation is one of the most important equations in physics, and is crucial for engineers studying the vibrations in vehicles and the response of buildings to earthquakes. And the equation at the heart of Information Theory, devised by Claude Shannon, is the basis of digital communication today.An approachable and informative guide to the equations upon which nearly every aspect of scientific and mathematical understanding depends, In Pursuit of the Unknown is also a reminder that equations have profoundly influenced our thinking and continue to make possible many of the advances that we take for granted.

    Christian Encounters, a series of biographies from Thomas Nelson Publishers, highlights important lives from all ages and areas of the Church through prose as accessible and concise as it is personal and engaging. Some are familiar faces. Others are unexpected guests. Whether the person is Galileo, William F. Buckley, John Bunyan, or Isaac Newton, we are now living in the world that they created and understand both it and ourselves better in the light of their lives. Their relationships, struggles, prayers, and desires uniquely illuminate our shared experience.HERO OR HERETIC? GENIUS OR BLASPHEMER?It's no mystery how profound a role Galileo played in the Scientific Revolution. Less explored is the Italian innovator's sincere, guiding faith in God. In this exhaustively researched biography that reads like a page-turning novel, Mitch Stokes draws on his expertise in philosophy, logic, math, and science to attune modern ears with Galileo's controversial genius.Emerging from the same Florentine milieu that produced Dante, da Vinci, Machiavelli, Michelangelo, Amerigo Vespuci, Galileo questioned with a persistence that spurred his world toward an unabating era of discovery. Stokes confronts the myth that Galileo's stance on heliocentricity stood astride a church vs. science divide and explores his calculations for the dimensions of Dante's hell, his understanding of motion, and his invention of the pendulum clock.To read this volume is to journey through Galileo's remarkable life: from his inquisitive childhood to his dying days, when, although blind and decrepit, he soldiered on, dictating mathematical thoughts and mentoring young proteges.

    The Seven Deadly Virtues sits down next to readers at the bar, buys them a drink, and an hour or three later, ushers them into the revival tent without them even realizing it.   The book’s contributors include Sonny Bunch, Christopher Buckley, David “Iowahawk” Burge, Christopher Caldwell, Andrew Ferguson, Jonah Goldberg, Michael Graham, Mollie Hemingway, Rita Koganzon, Matt Labash, James Lileks, Rob Long, Larry Miller, P. J. O’Rourke, Joe Queenan, Christine Rosen, and Andrew Stiles. Jonathan V. Last, senior writer at the Weekly Standard, editor of the collection, is also a contributor. All eighteen essays in this book are appearing for the first time anywhere.   In the book’s opening essay, P. J. O’Rourke observes: “Virtue has by no means disappeared. It’s as much in public view as ever. But it’s been strung up by the heels. Virtue is upside down. Virtue is uncomfortable. Virtue looks ridiculous. All the change and the house keys are falling out of Virtue’s pants pockets.”   Here are the virtues everyone (including the book’s contributors) was taught in Sunday school but have totally forgotten about until this very moment.  In this sanctimony-free zone:   • Joe Queenan observes: “In essence, thrift is a virtue that resembles being very good at Mahjong. You’ve heard about people who can do it, but you’ve never actually met any of them.” • P. J. O’Rourke notes: “Fortitude is quaint. We praise the greatest generation for having it, but they had aluminum siding, church on Sunday, and jobs that required them to wear neckties or nylons (but never at the same time). We don’t want those either.” • Christine Rosen writes: “A fellowship grounded in sociality means enjoying the company of those with whom you actually share physical space rather than those with whom you regularly and enthusiastically exchange cat videos.” • Rob Long offers his version of modern day justice: if you sleep late on the weekend, you are forced to wait thirty minutes in line at Costco. • Jonah Goldberg offers: “There was a time when this desire-to-do-good-in-all-things was considered the only kind of integrity: ‘Angels are better than mortals. They’re always certain about what is right because, by definition, they’re doing God’s will.’ Gabriel knew when it was okay to remove a mattress tag and Sandalphon always tipped the correct amount.” • Sonny Bunch dissects forbearance, observing that the fictional Two Minutes Hate of George Orwell’s 1984 is now actually a reality directed at living, breathing people. Thanks, in part, to the Internet, “Its targets are designated by a spontaneously created mob—one that, due to its hive-mind nature—is virtually impossible to call off.”   By the time readers have completed The Seven Deadly Virtues, they won’t even realize that they’ve just been catechized into an entirely different—and better—moral universe.

    Some Christians today, however, readily dismiss the historical consensus, arguing that those same Christians also believed the earth was the center of the universe. Understandably, there are reasons to doubt the traditional view . . . and yet rarely are those doubts humbly subjected to serious scholarship.C. John Collins invites both doubts and scholarship to the table. Applying well-informed, critical thinking to questions raised by theologians and scientists alike, Collins examines the historicity and relevance of a real Adam and Eve, ultimately answering the questions: Did Adam and Eve really exist? And why should we care?

    On March 24, 1988, at the University of Mississippi, J.P. Moreland, a leading Christian philosopher and ethicist, and Kai Nielsen, one of today's best-known atheist philosophers, went head-to-head over these questions. Does God Exist? records their entire lively debate and includes questions from the audience, the debaters' answers, and the responses of four recognized scholars - William Lane Craig, Antony Flew, Dallas Willard, and Keith Parsons. Noted author and philosopher Peter Kreeft has written an introduction, concluding chapter, and appendix - all designed to help readers decide for themselves whether God is fact or fantasy.

    Richard Carrier, world renowned philosopher and historian, explains the four reasons he does not accept the Christian religion, describing four facts of the world that, had they been different, he would believe. He is brief, clear, and down to earth, covering the whole topic in under ninety pages of easy-to-read explanation. Those four reasons are God's silence, God's inaction, the lack of evidence, and the way the universe looks exactly like a godless universe would, and not at all like a Christian universe would, even down to its very structure. Dr. Carrier addresses all the usual replies to these claims, in ways you might not have heard before, relying on his wide experience in debating and studying these issues all over the world for more than fifteen years. A perfect book to introduce yourself, or your friends, to why fewer educated people are embracing Christianity than ever before. Ideal for handing out to door-to-door missionaries.

    Lewis, always “Jack” to family and friends, never shied from intellectual debate, and through his written works encouraged others to wrestle with the difficult questions of faith. A master of visual illustration and allegory, Lewis wrote with the intuitive understanding that his readers wrestled with the same questions about the Christian story, about pain, suffering, and notions of Heaven and Hell, as he himself had wrestled. He also understood that others found reason and imagination to be incompatible aspects of an understanding of God and the universe.

    Latter-day Saints have long been encouraged to stay on the covenant path—but what is that path, and how do we stay the course? In God Will Prevail: Ancient Covenants, Modern Blessings, and the Gathering of Israel, BYU Professor of Religion Dr. Kerry Muhlestein encourages readers to take hold of God’s promise to gather His covenant people by recognizing the connection between covenant making and the eternal and transformative love of the Savior. Discover the obligations and blessings of making and keeping sacred covenants, as outlined in the standard works, with insights on topics ranging from temple work and family history to covenant language, the gathering of Israel, and the equalizing power of Christ’s Atonement. With clarity and hope, this groundbreaking book speaks to this powerful truth: promised blessings and gatherings are available to all who truly seek to be covenant keepers.

    How does Jane Goodall’s relationship with her dog Rusty inform her thinking about our relationship to other species? Which time and place would Jared Diamond most prefer to live in, in light of his work on the role of chance in history? What does driving a sports car have to do with Steven Weinberg’s quest for the “theory of everything”? Physicist and journalist Stefan Klein’s intimate conversations with nineteen of the world’s best-known scientists (including three Nobel Laureates) let us listen in as they talk about their paradigm-changing work—and how it is deeply rooted in their daily lives. • Cosmologist Martin Rees on the beginning and end of the world • Evolutionary biologist Richard Dawkins on egoism and selflessness • Neuroscientist V. S. Ramachandran on consciousness • Molecular biologist Elizabeth Blackburn on aging • Philosopher Peter Singer on morality • Physician and social scientist Nicholas Christakis on human relationships • Biochemist Craig Venter on the human genome • Chemist and poet Roald Hoffmann on beauty

    Yet often our most deeply felt longings—for meaning, for love, for significance—end up leading us away from, instead of toward, our Creator and the person he made us to be.  Finding Your Way Back to God shows you how to understand and listen to your longings in a whole new way. It’s about waking up to who you really are, and daring to believe that God wants to be found even more than you want to find him. It’s about making the biggest wager of your life as you ask God to make himself known to you. And it’s about watching what happens next.

    Christendom, according to Malcolm Muggeridge, is something quite different than Christianity. Christ said his kingdom was not of this world; Christendom, on the other hand, is of this world and, like every other human creation, subject to decay and eventual desolation. In this book, Muggeridge perceptively explores the downfall of Christendom, indicating some of the contributing factors to its collapse.

    Love is, as everyone knows, a mysterious and all-controlling force, with vast power over our thoughts and life decisions.But is there something a bit worrisome about all this uniformity of opinion? Is this the one subject about which no disagreement will be entertained, about which one truth alone is permissible? Consider that the most powerful organized religions produce the occasional heretic; every ideology has its apostates; even sacred cows find their butchers. Except for love.Hence the necessity for a polemic against it. A polemic is designed to be the prose equivalent of a small explosive device placed under your E-Z-Boy lounger. It won't injure you (well not severely); it's just supposed to shake things up and rattle a few convictions.

    A much-needed rejoinder to those who dream of an easy alliance between the two faiths.

    Now this instant classic has been completely updated, outfitted with a whole new arsenal of indispensable knowledge on global affairs, popular culture, economic trends, scientific principles, and modern arts. Here's your chance to brush up on all those subjects you slept through in school, reacquaint yourself with all the facts you once knew (then promptly forgot), catch up on major developments in the world today, and become the Renaissance man or woman you always knew you could be! How do you tell the Balkans from the Caucasus? What's the difference between fission and fusion? Whigs and Tories? Shiites and Sunnis? Deduction and induction? Why aren't all Shakespearean comedies necessarily thigh-slappers? What are transcendental numbers and what are they good for? What really happened in Plato's cave? Is postmodernism dead or just having a bad hair day? And for extra credit, when should you use the adjective continual and when should you use continuous? An Incomplete Education answers these and thousands of other questions with incomparable wit, style, and clarity. American Studies, Art History, Economics, Film, Literature, Music, Philosophy, Political Science, Psychology, Religion, Science, and World History: Here's the bottom line on each of these major disciplines, distilled to its essence and served up with consummate flair.

    Two long essays: “The Idea of a Christian Society” (on the direction of religious thought toward criticism of political and economic systems) and “Notes towards the Definition of Culture” (on culture, its meaning, and the dangers threatening the legacy of the Western world).
