Was there only one cometary or meteoric impact that apparently caused the death of the dinosaurs? There were several and some were much larger than we are led to believe. Our planets history is much stranger than we are led to believe.
From bestselling and award-winning author T.C. Boyle, a lively, thought-provoking novel that asks us what it would be like if we could really talk to the animals When animal behaviorist Guy Schermerhorn demonstrates on a TV game show that he has taught Sam, his juvenile chimp, to speak in sign language, Aimee Villard, an undergraduate at Guy's university, is so taken with the performance that she applies to become his assistant. A romantic and intellectual attachment soon morphs into an interspecies love triangle that pushes hard at the boundaries of consciousness and the question of what we know and how we know it. What if it were possible to speak to the members of another species—to converse with them, not just give commands or coach them but to really have an exchange of ideas and a meeting of minds? Did apes have God? Did they have souls? Did they know about death and redemption? About prayer? The economy, rockets, space? Did they miss the jungle? Did they even know what the jungle was? Did they dream? Make wishes? Hope for the future? These are some the questions T.C. Boyle asks in his wide-ranging and hilarious new novel Talk to Me, exploring what it means to be human, to communicate with another, and to truly know another person—or animal…
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.
Humans have always been fascinated by the possibility of extraterrestrial life, often wondering if we are alone in the universe. Drawing on nearly fifty years as a leader in planetary exploration, Louis Friedman brings into focus the subject of extraterrestrial life, separating knowledge from conjecture, fact from fiction, to draw scientific and technical conclusions that answer this enduring question. Friedman argues that intelligent life is probably rare in the universe (maybe even uniquely on Earth) but that simple life is likely abundant on millions or billions of planets waiting now to be discovered. He asserts that studying and searching for extraterrestrial life cannot be done by interstellar probes—due to the vastness of space and the comparative brevity of human lifespans—but it can be done remotely by a new technique involving the solar gravity lens that can magnify exoplanets by tens of billions. This technique will allow humankind to explore exoplanets and open up an exciting new field of comparative astrobiology. Wide-ranging in scope, this book discusses the history of searching for extraterrestrial life, the scientific evidence thereof, and finally his own conclusions on what’s next. Included in the book are three appendices: an explanation of interstellar messaging, a reprint of a debate between Carl Sagan and Ernst Mayr on extraterrestrial intelligence, and an opinion essay on the search for extraterrestrial intelligence.
“Takes readers on illuminating scientific adventure, beginning sixty-six million years ago, that connects dinosaurs, comets, DNA, and the future of the planet.” —Huffington Post In this brilliant exploration of our cosmic environment, the renowned particle physicist and New York Times–bestselling author of Warped Passages and Knocking on Heaven’s Door uses her research into dark matter to illuminate the startling connections between the furthest reaches of space and life here on Earth. Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it might have been dark matter that killed the dinosaurs. Working through the background and consequences of this proposal, Randall shares with us the latest findings—established and speculative—regarding the nature and role of dark matter and the origin of the Universe, our galaxy, our Solar System, and life, along with the process by which scientists explore new concepts. In Dark Matter and the Dinosaurs, Randall tells a breathtaking story that weaves together the cosmos’ history and our own, illuminating the deep relationships that are critical to our world and the astonishing beauty inherent in the most familiar things. “Randall has woven a beautiful account of how life on Earth is intimately connected to the cosmos.” —The Daily Telegraph (UK)
Although about 70 percent of known terrestrial meteorite impacts involve sedimentary rocks, the response of such rock to hyper- velocity impact is not well understand. Evans (Missouri State U., Springfield) introduces a dozen papers from a session on impact geology at the 2004 Geological Society of America Annual Meeting. Arranged by rocks' stratigraphic order (oldest to youngest) in proximal and distal settings, papers study topics including: characterization of impact sediments; a model for impact cratering processes; development of breccias (rock composed of sharp fragments embedded in a fine- grained matrix) in the Chesapeake Bay impact structure; and the method of impact stratigraphy applied to aging of the K-T boundary associated with mass extinction. The well-illustrated volume is not indexed.
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”.
This new collection of short stories from T.C. Boyle finds him at his mercurial best. Inventive, wickedly funny, sometimes disturbing, these are stories about drop-outs, deadbeats and kooks. Take the man who shares his apartment with a wildcat won in a drunken bet; the drive-time shock jock hallucinating from sleep deprivation for a publicity stunt; the suburban woman who joins a pack of dogs, eating rabbits and baying at the moon. With a unique deftness of touch and a keen eye for the telling detail, Boyle has mapped the strange underworld of America.
This is a marvellously engaging tour covering the whole of modern science, from transgenic crops to quantum tangles. Written by one of the most experienced and well-known names in science writing, it is also assuredly reliable science. Although arranged for convenience and quick reference as a collection of topics in alphabetical order, it is very different from any conventional encyclopedia. Each topic tells a story, making the book eminently browsable. Packed with information, yet carrying its immense learning lightly, this is a book that would appeal to anyone with the slightest interest in how the world works.
Used widely in non-majors biology classes, The Tangled Bank is the first textbook about evolution intended for the general reader. Zimmer, an award-winning science writer, takes readers on a fascinating journey into the latest discoveries about evolution. In the Canadian Arctic, paleontologists unearth fossils documenting the move of our ancestors from sea to land. In the outback of Australia, a zoologist tracks some of the world’s deadliest snakes to decipher the 100-million-year evolution of venom molecules. In Africa, geneticists are gathering DNA to probe the origin of our species. In clear, non-technical language, Zimmer explains the central concepts essential for understanding new advances in evolution, including natural selection, genetic drift, and sexual selection. He demonstrates how vital evolution is to all branches of modern biology—from the fight against deadly antibiotic-resistant bacteria to the analysis of the human genome.
