But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. The very latest discoveries in paleontology--many of them made by the author and his students--are integrated with emerging insights from molecular biology and earth system science to forge a broad understanding of how the biological diversity that surrounds us came to be. Moving from Siberia to Namibia to the Bahamas, Knoll shows how life and environment have evolved together through Earth's history. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. Readers go into the field to confront fossils, enter the lab to discern the inner workings of cells, and alight on Mars to ask how our terrestrial experience can guide exploration for life beyond our planet. Along the way, Knoll brings us up-to-date on some of science's hottest questions, from the oldest fossils and claims of life beyond the Earth to the hypothesis of global glaciation and Knoll's own unifying concept of ''permissive ecology.'' In laying bare Earth's deepest biological roots, Life on a Young Planet helps us understand our own place in the universe--and our responsibility as stewards of a world four billion years in the making.In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication.

    But it doesn't have to be this way. In City Dharma, Arthur Jeon suggests that it’s not what happens to us, but how we react to events and thoughts that causes most of our suffering.City Dharma is the essential guide for everyone living in the accelerated world most of us call home. Offering smart, practical ways to overcome daily stresses and the crazy-making reactivity of our own minds, Jeon explores the most challenging aspects of modern urban and suburban life, including:Another Day, Another DollarAvoid Working StiffnessWalking Down a Dark AlleyAwareness and Violence Sex and the City DharmaSeeking Love vs. Expressing LoveScaring Ourselves to DeathTranscending Media NegativityRoad RageDealing with Mad Max Within and WithoutDrawing wisdom from the ancient Eastern teachings of Advaita Vedanta and filled with engaging stories, City Dharma offers a new way of seeing the world--one that is based on connection rather than separation, direct experience rather than belief, and love instead of fear.From the Hardcover edition.

    The adjective 'medieval' has become a synonym for brutality and uncivilized behavior. Yet without the work of medieval scholars there could have been no Galileo, no Newton and no Scientific Revolution. In God's Philosophers, James Hannam debunks many of the myths about the Middle Ages, showing that medieval people did not think the earth is flat, nor did Columbus 'prove' that it is a sphere; the Inquisition burnt nobody for their science nor was Copernicus afraid of persecution; no Pope tried to ban human dissection or the number zero. God's Philosophers is a celebration of the forgotten scientific achievements of the Middle Ages - advances which were often made thanks to, rather than in spite of, the influence of Christianity and Islam. Decisive progress was also made in technology: spectacles and the mechanical clock, for instance, were both invented in thirteenth-century Europe. Charting an epic journey through six centuries of history, God's Philosophers brings back to light the discoveries of neglected geniuses like John Buridan, Nicole Oresme and Thomas Bradwardine, as well as putting into context the contributions of more familiar figures like Roger Bacon, William of Ockham and Saint Thomas Aquinas.

    But soon, Earth's isolation could come to an end. Over the past two decades, astronomers have discovered thousands of planets orbiting other stars. Some of these exoplanets may be mirror images of our own world. And more are being found all the time.Yet as the pace of discovery quickens, an answer to the universe's greatest riddle still remains just out of reach: Is the great silence and emptiness of the cosmos a sign that we and our world are somehow singular, special, and profoundly alone, or does it just mean that we’re looking for life in all the wrong places? As star-gazing scientists come closer to learning the truth, their insights are proving ever more crucial to understanding life’s intricate mysteries and possibilities right here on Earth.Science journalist Lee Billings explores the past and future of the "exoplanet boom" through in-depth reporting and interviews with the astronomers andplanetary scientists at its forefront. He recounts the stories behind their world-changing discoveries and captures the pivotal moments that drove them forward in their historic search for the first habitable planets beyond our solar system. Billings brings readers close to a wide range of fascinating characters, such as:FRANK DRAKE, a pioneer who has used the world’s greatest radio telescopes to conduct the first searches for extraterrestrial intelligence and to transmit a message to the stars so powerful that it briefly outshone our Sun.JIM KASTING, a mild-mannered former NASA scientist whose research into the Earth’s atmosphere and climate reveals the deepest foundations of life on our planet, foretells the end of life on Earth in the distant future, and guides the planet hunters in their search for alien life.SARA SEAGER, a visionary and iron-willed MIT professor who dreams of escaping the solar system and building the giant space telescopes required to discover and study life-bearing planets around hundreds of the Sun’s neighboring stars.Through these and other captivating tales, Billings traces the triumphs, tragedies, and betrayals of the extraordinary men and women seeking life among the stars. In spite of insufficient funding, clashing opinions, and the failings of some of our world’s most prominent and powerful scientific organizations, these planet hunters will not rest until they find the meaning of life in the infinite depths of space. Billings emphasizes that the heroic quest for other Earth-like planets is not only a scientific pursuit, but also a reflection of our own culture’s timeless hopes and fears.

    Yet, while we hear these pleas, we're already functioning with existing beliefs—even if they are beliefs by default. So how do we choose what to believe—especially in the area of faith? Do we need to choose? In "Choosing Your Faith, " Mark Mittelberg encourages us, as Socrates does, not to lead an unexamined life. He invites us to examine why we believe what we believe. This examination will resonate with Christians and seekers alike.

    Can our world support that? What kind of world will it be? Those answering these questions generally fall into two deeply divided groups--Wizards and Prophets, as Charles Mann calls them in this balanced, authoritative, nonpolemical new book. The Prophets, he explains, follow William Vogt, a founding environmentalist who believed that in using more than our planet has to give, our prosperity will lead us to ruin. Cut back! was his mantra. Otherwise everyone will lose! The Wizards are the heirs of Norman Borlaug, whose research, in effect, wrangled the world in service to our species to produce modern high-yield crops that then saved millions from starvation. Innovate! was Borlaug's cry. Only in that way can everyone win! Mann delves into these diverging viewpoints to assess the four great challenges humanity faces--food, water, energy, climate change--grounding each in historical context and weighing the options for the future. With our civilization on the line, the author's insightful analysis is an essential addition to the urgent conversation about how our children will fare on an increasingly crowded Earth.

    Konrad Lorenz was gifted with a similar power of understanding the animal world. He was that rare beast, a brilliant scientist who could write (and indeed draw) beautifully. He did more than any other person to establish and popularize the study of how animals behave, receiving a Nobel Prize for his work. King Solomon's Ring, the book which brought him worldwide recognition, is a delightful treasury of observations and insights into the lives of all sorts of creatures, from jackdaws and water-shrews to dogs, cats and even wolves. Charmingly illustrated by Lorenz himself, this book is a wonderfully written introduction to the world of our furred and feathered friends, a world which often provides an uncanny resemblance to our own. A must for any animal-lover!

    Published at Mother Teresa's personal request to share her message with the world, it contains personal stories, revealing insights and never-before-seen letters from Mother Teresa.

    Why?In this book, I argue that the root of the problem is America’s religiosity. A crisis that only science could meet threatened to expose the impotence of religious claims, and religious leaders and institutions went on the attack. Any hope of a rational, scientifically informed response was crippled by a presidential administration elected by religious zealots, staffed by religious zealots, and beholden to religious zealots. But their malfeasance was not limited to the political arena.From churches ignoring state lock downs, to televangelists declaring the disease miraculously eradicated, to pastors suing their governors for enforcing public safety measures, religion was at the forefront of virtually every misguided step towards catastrophe that the nation took.When science eventually solves this problem, religions will be quick to thank their gods for the scientist’s labor and forgive themselves their trespasses. We cannot afford to give them such easy absolution. Their disastrous contributions to our national pandemic response are a potent reminder that a nation in the twenty-first century can ill afford to let anyone compete with science in the realm of truth.

    There is much about the end of history we don't understand. But while thoughts on the final day will stir our questions, they needn't stir our fears. Regarding that day, Jesus urged, Don't let your hearts be troubled. Trust in God, and trust in me (John 14:1).Max Lucado believes the day Christ comes will be the beginning of the very best. And our primary task is to be prepared and peaceful while we wait.If we have some questions about the end of time ...If we have concerns about what will happen to us ...If we want to look to the end of times as a source of comfort and not chaos ...Then this is the book we need. New York Times best-selling author Max Lucado walks us through Scripture to find peace in the present and hope for the hereafter.

    Over the past decade, the world has seen the most powerful El Ni�o ever recorded, the most devastating hurricane in two hundred years, the hottest European summer on record, and one of the worst storm seasons ever experienced in Florida. With one out of every five living things on this planet committed to extinction by the levels of greenhouse gases that will accumulate in the next few decades, we are reaching a global climatic tipping point. The Weather Makers is both an urgent warning and a call to arms, outlining the history of climate change, how it will unfold over the next century, and what we can do to prevent a cataclysmic future. Along with a riveting history of climate change, Tim Flannery offers specific suggestions for action for both lawmakers and individuals, from investing in renewable power sources like wind, solar, and geothermal energy, to offering an action plan with steps each and every one of us can take right now to reduce deadly CO2 emissions by as much as 70 percent.

    Even as a teenager, experimenting in his own laboratory, he was impressed by the logic and materiality of the universe, which is governed by a small number of disembodied forces and laws. Those laws decree that all things in the world are material and impermanent. But one summer evening, while looking at the stars from a small boat at sea, Lightman was overcome by the overwhelming sensation that he was merging with something larger than himself--a grand and eternal unity, a hint of something absolute and immaterial. Searching for Stars on an Island in Maine is the result of these seemingly contradictory impulses, written as an extended meditation on an island in Maine, where Lightman and his wife spend their summers. Framing the dialogue between religion and science as a contrast between absolutes and relatives, Lightman explores our human quest for truth and meaning and the different methods of religion and science in that quest. Along the way, he draws from sources ranging from St. Augustine's conception of absolute truth to Einstein's relativity, from a belief in the divine and eternal nature of stars to their discovered materiality and mortality, from the unity of the once indivisible atom to the multiplicity of subatomic particles and the recent notion of multiple universes. What emerges is not only an understanding of the encounter between science and religion but also a profound exploration of the complexity of human existence.

    This book contains the teachings and meditations Lama gave at a five-day retreat he led near Melbourne, Australia, which he introduced by saying: "Whether or not this five-day meditation course becomes beneficial is up to you; it depends on your own mind. It's not a lama thing; I'm not going to bring you to enlightenment in this short time... If over the next five days you can begin to recognize the reality of your own nature, this meditation course will have been worthwhile. Therefore, dedicate your actions during this time to discovering inner freedom through recognizing the negative characteristics of your own uncontrolled mind."

    She entered Ah-gwah-ching State Sanatorium at Walker, Minnesota, for what she thought would be a short stay. In January, her tuberculosis spread, and she nearly died. Her recovery required many months of bed rest and medical care.Marilyn loved to write, and the story of her three-year residency at the sanatorium is preserved in hundreds of letters that she mailed back home to her parents, who could visit her only occasionally and whom she missed terribly. The letters functioned as a diary in which Marilyn articulately and candidly recorded her reactions to roommates, medical treatments, Native American nurses, and boredom. She also offers readers the singular perspective of a bed-bound teenager, gossiping about boys, requesting pretty new pajamas, and enjoying Friday evening popcorn parties with other patients.Selections from this cache of letters are woven into an informative narrative that explores the practices and culture of a midcentury tuberculosis sanatorium and fills in long-forgotten details gleaned from recent conversations with Marilyn, who "graduated" from the sanatorium and went on to lead a full, productive life.
