Luis and Walter Alvarez



Luis (1911-1988) and Walter Alvarez (1940-) were a father and son team who publicized that a layer of iridium (a rare element that mostly comes from asteroids) rich clay, had been found worldwide at rocks marking the ending of the Cretaceous period (the K-T boundary). This iridium layer is supportive of the asteriod impact extinction theory.

Previously, Luis Alvarez had won a Nobel Prize (1968) for his other work on subatomic physics.

Product Description:

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.

Product Description:

"A thrilling synthesis from a brilliant scientist who discovered one of the most important chapters in our history." ―Sean B. 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.

Product Description:

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.

Product Description:
Endangered Species Recovery presents case studies of prominent species recovery programs in an attempt to explore and analyze their successes, failures, and problems, and to begin to find ways of improving the process. It is the first effort to engage social scientists as well as biologists in a wide-ranging analysis and discussion of endangered species conservation, and provides valuable insight into the policy and implementation framework of species recovery programs. The book features a unique integration of case studies with theory, and provides sound, practical ideas for improving endangered species policy implementation.
