Download or read book T. rex and the Crater of Doom written by Walter Alvarez and published by Princeton University Press. This book was released on 2015-09-15 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sixty-five million years ago, a comet or asteroid larger than Mount Everest slammed into the Earth, inducing an explosion equivalent to the detonation of a hundred million hydrogen bombs. Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half the plant and animal genera on Earth had perished. This horrific chain of events is now widely accepted as the solution to a great scientific mystery: what caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.

Book Synopsis Chicxulub: The Impact and Tsunami by : David Shonting
Download or read book Chicxulub: The Impact and Tsunami written by David Shonting and published by Springer. This book was released on 2016-09-09 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book tells the story of the catastrophic impact of the giant 10 Km asteroid Chicxulub into the ancient Gulf of Mexico 65.5 million years ago. The book begins with a discussion of the nature of asteroids and the likelihood of future Earth-impacts. The story then turns to the discovery of a global sediment layer attributed to the fallout from the impact and a piecing together of the evidence that revealed a monster crater, buried under the Gulf. Reviewed is the myriad of geological and fossil evidence that suggested the disastrous sequence of events occurring when a "nuclear-like" explosion ripped through the sea, Earth, and atmosphere, thus forming the mega-crater and tsunami. The aftermath of the Chicxulub's event initiated decades and more of major global climate changes including a "Nuclear Winter" of freezing darkness and blistering greenhouse warming. A chapter is dedicated to the science of tsunamis and their model generation, including a portrayal of the globally rampaging Chicxulub waves. The asteroid's global devastation killed off some 70% of animal and plant life including the dinosaurs. The study of an ancient Cambrian fossil bed suggests how "roll of the dice" events can affect the future evolution of life on Earth. We see how Chicxulub's apparent destruction of the dinosaurs, followed by the their replacement with small mammals, altered forever the progress of human evolution. This book presents a fascinating glimpse through the lens of the natural sciences - the geology, climatology, and oceanography, of the effects of an enormous astronomical event.
Download or read book The God Con written by Lee Moller and published by FriesenPress. This book was released on 2017-06-24 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The crucifix is in! You can fool most of the people most of the time. In The God Con, Lee Moller, a life-long atheist and skeptic, looks at organized religion through the lens of the con. Organized religion has been selling an invisible product, that it never has to deliver, for thousands of years. It has given us bigotry, rampant pedophilia, terrorism, and bloodshed beyond imagining. And its acolytes have, in turn, given organized religion power over their bank accounts, their reproduction, and their very “souls”.

Carroll Big History, the field that integrates traditional historical scholarship with scientific insights to study the full sweep of our universe, has so far been the domain of historians. Famed geologist Walter Alvarez—best known for the “Impact Theory” explaining dinosaur extinction—has instead championed a science-first approach to Big History. Here he wields his unique expertise to give us a new appreciation for the incredible occurrences—from the Big Bang to the formation of supercontinents, the dawn of the Bronze Age, and beyond—that have led to our improbable place in the universe.
Book Synopsis Night Comes to the Cretaceous by : James Lawrence Powell
Download or read book Night Comes to the Cretaceous written by James Lawrence Powell and published by Mariner Books. This book was released on 1999 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: What killed the dinosaurs? For more than a century, this question has been one of the greatest unsolved mysteries in science. But, in 1980, Nobel Prize-winning physicist Luis Alvarez and his son, Walter, proposed a radical answer: 65 million years ago an asteroid or comet as big as Mt. Everest slammed into the earth, raising a dust cloud vast enough to cause mass extinction. A revolutionary idea that challenged the ice-age extinction theory, the asteroid-impact theory was scorned and derided by the science community. But after years of bitter debate and intense research, an astonishing discovery was made-an immense impact crater in the Yucatan Peninsula that was identified as Ground Zero. The Alvarezes had their proof. A dramatic scientific detective story, Night Comes to the Cretaceous is a brilliant example of science at work-in the trenches, complete with passionate struggles and occasional victories. "
Download or read book Cosmic Impact written by Andrew May and published by Icon Books. This book was released on 2019-02-07 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: As end-of-the-world scenarios go, an apocalyptic collision with an asteroid or comet is the new kid on the block, gaining respectability only in the last decade of the 20th century with the realisation that the dinosaurs had been wiped out by just such an impact. Now the science community is making up for lost time, with worldwide efforts to track the thousands of potentially hazardous near-Earth objects, and plans for high-tech hardware that could deflect an incoming object from a collision course – a procedure depicted, with little regard for scientific accuracy, in several Hollywood movies. Astrophysicist and science writer Andrew May disentangles fact from fiction in this fast-moving and entertaining account, covering the nature and history of comets and asteroids, the reason why some orbits are more hazardous than others, the devastating local and global effects that an impact event would produce, and – more optimistically – the way future space missions could avert a catastrophe.
Download or read book Extinction written by Douglas H. Erwin and published by Princeton University Press. This book was released on 2015-03-22 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some 250 million years ago, the earth suffered the greatest biological crisis in its history. Around 95 percent of all living species died out—a global catastrophe far greater than the dinosaurs' demise 185 million years later. How this happened remains a mystery. But there are many competing theories. Some blame huge volcanic eruptions that covered an area as large as the continental United States; others argue for sudden changes in ocean levels and chemistry, including burps of methane gas; and still others cite the impact of an extraterrestrial object, similar to what caused the dinosaurs' extinction. Extinction is a paleontological mystery story. Here, the world's foremost authority on the subject provides a fascinating overview of the evidence for and against a whole host of hypotheses concerning this cataclysmic event that unfolded at the end of the Permian. After setting the scene, Erwin introduces the suite of possible perpetrators and the types of evidence paleontologists seek. He then unveils the actual evidence--moving from China, where much of the best evidence is found; to a look at extinction in the oceans; to the extraordinary fossil animals of the Karoo Desert of South Africa. Erwin reviews the evidence for each of the hypotheses before presenting his own view of what happened. Although full recovery took tens of millions of years, this most massive of mass extinctions was a powerful creative force, setting the stage for the development of the world as we know it today. In a new preface, Douglas Erwin assesses developments in the field since the book's initial publication.
Book Synopsis The Great Dinosaur Extinction Controversy by : Charles Officer
Download or read book The Great Dinosaur Extinction Controversy written by Charles Officer and published by Addison Wesley Publishing Company. This book was released on 1996-06-30 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1980 Nobel Laureate Luis Alvarez announced his theory of the dinosaurs final demise: a gigantic meteorite crashed into the earth and raised a cloud of dust that caused darkness for years, suppressing photosynthesis, which impeded plant growth, and eventually starved the dinosaurs. This idea exploded into common awareness with almost unprecedented speed, and was instantly embraced by the media and the public. Almost without question, it quickly became the hottest scientific "fact". Unfortunately for Alvarez, many in the scientific community did to support this theory, and in fact later research showed the impossibility of such an idea. The Great Dinosaur Extinction Controversy chronicles the fantastic story of how this hypothesis became so widespread, the way it became "common knowledge" - from the pages of Science to The New York Times to Parade Magazine, the controversy it caused, and the ample scientific research that proves the theory wrong. Officer and Page also present an attractive and carefully investigated alternative explanation for the mass extinctions that occurred at the end of the Cretaceous period. Through this account they show the ways that sound science should be performed and the findings transmitted.
Book Synopsis The Worst of Times by : Paul B. Wignall
Download or read book The Worst of Times written by Paul B. Wignall and published by Princeton University Press. This book was released on 2017-05-09 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: 260 million years ago, life on Earth suffered wave after wave of cataclysmic extinctions, with the worst--the end-Permian extinction--wiping out nearly every species on the planet. This book delves into the mystery behind these extinctions and sheds light on the fateful role the primeval supercontinent, known as Pangea, may have played in causing these global catastrophes. Drawing on the latest discoveries as well as his own field expeditions to remote corners of the world, Paul Wignall reveals what scientists are only now beginning to understand about the most prolonged period of environmental crisis in Earth's history. He describes how a series of unprecedented extinction events swept across the planet in a span of eighty million years, rapidly killing marine and terrestrial life on a scale more devastating than the dinosaur extinctions that would come later. Wignall shows how these extinctions--some of which have only recently been discovered--all coincided with gigantic volcanic eruptions of flood basalt lavas that occurred when the world's landmasses were united into a single vast expanse. Unraveling one of the great enigmas of ancient Earth, this book also explains how the splitting apart of Pangea into the continents we know today ushered in a new age of vibrant and more resilient life on our planet.--Adapted from book jacket.
Book Synopsis The Behavior of the Earth by : Claude J. Allègre
Download or read book The Behavior of the Earth written by Claude J. Allègre and published by Harvard University Press. This book was released on 1988 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Well over a century after Darwin gave biology its unifying theory of evolution, the earth sciences experienced a similar revolution and the theory of plate tectonics took hold. Plate tectonics posed the idea that the earth's crust is divided into a number of large, thin plates always in motion relative to one another. In The Behavior of the Earth, world-renowned earth scientist Claude Allègre sets forth the exciting events in this contemporary revolution from its first stirrings in the nineteenth-century and Alfred Wegener's original model of continental drift (1912) through the development of its full potential in modern plate-tectonic theory. Few scientific theories have been so all-encompassing, and none has surpassed plate tectonics in explaining such a wide variety of geological phenomena, from the origins of mountain building to the formation of the ocean floor. As it integrated our knowledge of the earth's surface with the investigation of its interior, plate tectonics fused two previously autonomous strains of scientific inquiry. Continental mobility changed for all time our view of the earth from a static globe to an evolving, living planet, and allowed us to see that changes in the earth's surface are but exterior manifestations of a dynamic interplay of forces within the crust and the mantle.Allègre casts his lucid exposition of this scientific theory within the historical context of its struggle for acceptance. As he introduces us to the huge cast of personalities and researchers who contributed to the theory, he illuminates the complex role that the scientific community plays in the proliferation and acceptance of new ideas. Allègre is as insightful in discussing the human motivation for scientific endeavor as he is skillful in presenting the science that results from this effort. Richly illustrated and including a glossary, this book offers the reader rare access both to the central theory of plate tectonics and to the constellation of problems and possibilities that preoccupy earth scientists today.

Book Synopsis The Mountains of Saint Francis: Discovering the Geologic Events That Shaped Our Earth by : Walter Alvarez
Download or read book The Mountains of Saint Francis: Discovering the Geologic Events That Shaped Our Earth written by Walter Alvarez and published by W. W. Norton & Company. This book was released on 2008-12-17 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the world's leading geologists takes readers into Italy's Apennine Mountain Range—the Mountains of Saint Francis—on a journey to discover the fascinating secrets of the Earth's deep history. Modern geologists, Walter Alvarez among them, showed in the last decades of the twentieth century that the history of our planet has witnessed events profoundly more dramatic than even the most spectacular chapters in human history. More violent than wars, more life altering than revolutions—understanding the geologic events that have shaped the Earth's surface is the quest and the passion of geologists. In the knowledgeable and graceful prose of Alvarez, general readers are led to explore the many mysteries that our planet guards. The author has chosen Italy as a microcosm in which to explore this amazing past for several reasons. First, it is the land where the earliest geologists learned how to read the history of the Earth, written in nature’s rock archives. Second, it is where Alvarez and his Italian geological friends have continued to decipher the rock record, uncovering more historical episodes from the Earth’s past. And third, the lovely land of Italy is unusually rich in geological treasures and offers examples of the key processes that have created the landscapes of the entire world. The Mountains of Saint Francis begins in Rome. We discover that the landscape of Rome was built by violent volcanic eruptions in the very recent past, almost certainly witnessed by our human ancestors. Next we travel to Siena and come face to face with a fundamental discovery of the geologists—that much of the dry land that we currently inhabit was once underwater, beneath ancient seas or oceans. Then we stop in the small medieval city of Gubbio and contemplate the amazing secret that the limestone rocks kept hidden for 65 million years—that a huge asteroid smashed into the Earth, disrupting the environment so severely that the dinosaurs, and perhaps half of the other forms of life inhabiting the Earth at the time, disappeared forever, opening the way for the rise of the mammals and eventually of humans. The impact theory that came from those Italian limestones at Gubbio was one of the great geological discoveries of the twentieth century. Just as important to the field of geology was the theory of plate tectonics—the understanding that the outer layer of the Earth is divided into crustal plates that move around, sometimes carrying continents into collisions with one another, like the great collision between Italy and Europe that built the Alps. And yet, to explain the Mountains of Saint Francis requires something more than a collision between continents. These are mountains that are still jealously guarding the secret of their past, and in this book we go along with the geological detectives as they try to uncover that secret. It is a journey that has seen the land of Italy lifted out of the sea, squashed and folded, torn apart, left high and dry when the Mediterranean Sea evaporated away, and then flooded when the Atlantic waters poured back in. The story of the Earth's history is fascinating in its own right, but with Alvarez as the tour guide, the journey takes on a human dimension, full of stories about the landscape and history of Italy and about the great geologists who uncovered the deep past of this land. It is a journey recounted in warm tones and subtle colors, reflecting the transcendent beauty of Italy itself.
