Book 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.

Book Description
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 Description
"... are dinosaurs social constructs? Do we really know anything about dinosaurs? Might not all of our beliefs about dinosaurs merely be figments of the paleontological imagination? A few years ago such questions would have seemed preposterous, even nonsensical. Now they must have a serious answer." At stake in the "Science Wars" that have raged in academe and in the media is nothing less than the standing of science in our culture. One side argues that science is a "social construct," that it does not discover facts about the world, but rather constructs artifacts disguised as objective truths. This view threatens the authority of science and rejects science's claims to objectivity, rationality, and disinterested inquiry. Drawing Out Leviathan examines this argument in the light of some major debates about dinosaurs: the case of the wrong-headed dinosaur, the dinosaur "heresies" of the 1970s, and the debate over the extinction of dinosaurs. Keith Parsons claims that these debates, though lively and sometimes rancorous, show that evidence and logic, not arbitrary "rules of the game," remained vitally important, even when the debates were at their nastiest. They show science to be a complex set of activities, pervaded by social influences, and not easily reducible to any stereotype. Parsons acknowledges that there are lessons to be learned by scientists from their would-be adversaries, and the book concludes with some recommendations for ending the Science Wars.
