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.

    In the tradition of unsolved historical mysteries like David Grann's Killers of the Flower Moon and Douglas Preston's The Lost City of the Monkey God, Brian Muraresku’s 10-year investigation takes the reader through Greece, Germany, Spain, France and Italy, offering unprecedented access to the hidden archives of the Louvre and the Vatican along the way.In The Immortality Key, Muraresku explores a little-known connection between the best-kept secret in Ancient Greece and Christianity. This is the real story of the most famous human being who ever lived (Jesus) and the biggest religion the world has ever known. Today, 2.4 billion people are Christian. That's one third of the planet. But do any of them really know how it all started?Before Jerusalem, before Rome, before Mecca—there was Eleusis: the spiritual capital of the ancient world. It promised immortality to Plato and the rest of Athens's greatest minds with a very simple formula: drink this potion, see God. Shrouded in secrecy for millennia, the Ancient Greek sacrament was buried when the newly Christianized Roman Empire obliterated Eleusis in the fourth century AD.Renegade scholars in the 1970s claimed the Greek potion was psychedelic, just like the original Christian Eucharist that replaced it. In recent years, vindication for the disgraced theory has been quietly mounting in the laboratory. The rapidly growing field of archaeological chemistry has proven the ancient use of visionary drugs. And with a single dose of psilocybin, the psycho-pharmacologists at Johns Hopkins and NYU are now turning self-proclaimed atheists into instant believers. No one has ever found hard, scientific evidence of drugs connected to Eleusis, let alone early Christianity. Until now.Armed with key documents never before translated into English, convincing analysis, and a captivating spirit of quest, Muraresku mines science, classical literature, biblical scholarship and art to deliver the hidden key to eternal life, bringing us to what clinical psychologist William Richards calls "the edge of an awesomely vast frontier."Featuring a Foreword by Graham Hancock, the New York Times bestselling author of America Before: The Key to Earth's Lost Civilization.

    Later, as you're about to get back to work, a colleague taps you on the shoulder to chat. At home, screens get in the way of quality time with your family. Another day goes by, and once again, your most important personal and professional goals are put on hold.  What would be possible if you followed through on your best intentions? What could you accomplish if you could stay focused and overcome distractions? What if you had the power to become "indistractable"?  International best-selling author, former Stanford lecturer, and behavioral design expert, Nir Eyal, wrote Silicon Valley's handbook for making technology habit-forming. Five years after publishing Hooked, Eyal reveals distraction's Achilles' heel in his groundbreaking new book.  In Indistractable, Eyal reveals the hidden psychology driving us to distraction. He describes why solving the problem is not as simple as swearing off our devices: Abstinence is impractical and often makes us want more.  Eyal lays bare the secret of finally doing what you say you will do with a four-step, research-backed model. Indistractable reveals the key to getting the best out of technology, without letting it get the best of us.  Inside, Eyal overturns conventional wisdom and reveals: Why distraction at work is a symptom of a dysfunctional company culture - and how to fix it  What really drives human behavior and why "time management is pain management"  Why your relationships (and your sex life) depend on you becoming indistractable  How to raise indistractable children in an increasingly distracting world Empowering and optimistic, Indistractable provides practical, novel techniques to control your time and attention - helping you live the life you really want.

    This is an account of the world's greatest ‘intellectual virtuosos,' who are also humanity's greatest doubters and disbelievers, from the ancient Greek philosophers, Jesus, and the Eastern religions, to modern secular equivalents Marx, Freud and Darwin—and their attempts to reconcile the seeming meaninglessness of the universe with the human need for meaning,This remarkable book ranges from the early Greeks, Hebrew figures such as Job and Ecclesiastes, Eastern critical wisdom, Roman stoicism, Jesus as a man of doubt, Gnosticism and Christian mystics, medieval Islamic, Jewish and Christian skeptics, secularism, the rise of science, modern and contemporary critical thinkers such as Schopenhauer, Darwin, Marx, Freud, Nietzsche, the existentialists.

      In the past few years, a handful of scientists have been in a race to explain a disturbing aspect of our universe: only 4 percent of it consists of the matter that makes up you, me, our books, and every planet, star, and galaxy. The rest—96 percent of the universe—is completely unknown.   Richard Panek tells the dramatic story of how scientists reached this conclusion, and what they’re doing to find this "dark" matter and an even more bizarre substance called dark energy. Based on in-depth, on-site reporting and hundreds of interviews—with everyone from Berkeley’s feisty Saul Perlmutter and Johns Hopkins’s meticulous Adam Riess to the quietly revolutionary Vera Rubin—the book offers an intimate portrait of the bitter rivalries and fruitful collaborations, the eureka moments and blind alleys, that have fueled their search, redefined science, and reinvented the universe.

    It is an integral part of their marriage, child rearing, and community. In this daring new book, distinguished philosopher Daniel C. Dennett takes a hard look at this phenomenon and asks why. Where does our devotion to God come from and what purpose does it serve? Is religion a blind evolutionary compulsion or a rational choice? In "Breaking the Spell," Dennett argues that the time has come to shed the light of science on the fundamental questions of faith. In a spirited narrative that ranges widely through history, philosophy, and psychology, Dennett explores how organized religion evolved from folk beliefs and why it is such a potent force today. Deftly and lucidly, he contends that the "belief in belief" has fogged any attempt to rationally consider the existence of God and the relationship between divinity and human need."Breaking the Spell" is not an antireligious screed but rather an eyeopening exploration of the role that belief plays in our lives, our interactions, and our country. With the gulf between rationalists and adherents of "intelligent design" widening daily, Dennett has written a timely and provocative book that will be read and passionately debated by believers and nonbelievers alike.

    This book is a classic example.”—CHRISTOPHER HITCHENS author of God is Not Great“The most eloquent witness of internal delusion that I know—a triumphantly smiling refugee from the zany, surreal world of American fundamentalist Protestantism—is Dan Barker.”—RICHARD DAWKINS author of The God Delusion“Godless was a revelation to me. I don’t think anyone can match the (devastating!) clarity, intensity, and honesty which Dan Barker brings to the journey—faith to reason, childhood to growing up, fantasy to reality, intoxication to sobriety.”—OLIVER SACKS authors of MusicophiliaIn Godless, Barker recounts his journey from evangelical preacher to atheist activist, and along the way explains precisely why it is not only okay to be an atheist, it is something in which to be proud.”—MICHAEL SHERMER publisher of Skeptic Magazine“Godless is a fascinating memoir and a handbook for debunking theism. But most of all, it is a moving testimonial to one man’s emotional and intellectual rigor in acclaiming critical thinking.”—ROBERT SAPOLSKY author of Why Zebras Don’t Get Ulcers

    We profess it in our creed. We're taught that to bury and pray for the dead are corporal and spiritual works of mercy. We honor the dead in our Liturgy through the Rite of Christian burial. We do all of this, and more, because when Jesus Christ took on flesh for the salvation of our souls he also bestowed great dignity on our bodies. In Hope to Die: The Christian Meaning of Death and the Resurrection of the Body, Scott Hahn explores the significance of death and burial from a Catholic perspective. The promise of the bodily resurrection brings into focus the need for the dignified care of our bodies at the hour of death. Unpacking both Scripture and Catholic teaching, Hope to Die reminds us that we are destined for glorification on the last day.Our bodies have been made by a God who loves us. Even in death, those bodies point to the mystery of our salvation.

    The average Christian does not realize that there is an intellectual war going on in the universities and in the professional journals and scholarly societies. Christianity is being attacked from all sides as irrational or outmoded, and millions of students, our future generation of leaders have absorbed this viewpoint. This is a war which we cannot afford to lose.... "In addition to serving, like the rest of theology in general, as an expression of our loving God with all our minds, apologetics specifically serves to show to unbelievers the truth of the Christian faith, to confirm that faith to believers, and to reveal and explore the connections between Christian doctrine and other truths.... Apologetics... is a theoretical discipline that tries to answer the question, What rational defense can be given for the Christian faith?"This book by respected philosopher and theologian William Lane Craig has been thoroughly revised and updated to equip believers in the successful proclamation of biblical truth claims. The author gives careful attention to crucial questions and concerns, including: How Do I Know Christianity Is True?, The Absurdity of Life Without God, The Existence of God, The Problem of Miracles, and The Resurrection of Jesus.An invaluable scholarly resource for all committed defenders of the Christian faith.

    Among these questions the most important one of all sometimes gets lost: Is Islam true? With his new book author Peter Townsend invites you to accompany him on a journey through the foundational texts of the Muslim religion. In the process the truth-claims of Islam will be respectfully, honestly and impartially evaluated. Along the way the following questions will be asked: - Can the traditional Islamic historical accounts be trusted? - Is the Qur'an a 'Perfect Book, Perfectly Preserved'? - Was Muhammad indeed a 'Beautiful Pattern of Conduct'? The answers to these questions will not be sought from modern commentaries on Islam. Instead Questioning Islam goes straight to the classic sources of Islam namely the Qur'an, hadiths (traditions) and biographies of Muhammad. Questioning Islam is not an attempt to promote any other belief system or ideology. Its focus is simply on asking the hard questions about Islam that are all too often ignored or swept under the carpet. Simply put, if you have ever wondered whether the truth-claims of Islam can withstand critical scrutiny then this book is for you!
