Using this example as a springboard, David M. Raup leaps into an egaging discussion of the theories, assumptions, and difficulties associated with the science of species extinction. Woven is along the way are stories of the trilobite eye, tropical reefs, flying reptiles, and the fate of the heath hen on Martha's Vineyard, a very modern extinction.

    First Life travels the world, from Canada to Australia, Morocco to Scotland, to unearth the secrets hidden in prehistoric fossils and meet the palaeontologists who have harnessed new techniques to enhance greatly our understanding of the origins of life.With an introduction by David Attenborough, and insights captured during the making of the television series, this book is a journey of discovery, showing us what these early animals would have looked like and how they would have lived, bringing them to life with the help of modern computer technology. First Life shows us how evolutionary features of the first creatures have been passed down to modern animals, including humans, giving us amazing insight into the remarkable evolutionary journey that has brought us here today.

    To the right listener, they tell us all about themselves: where they came from, how they lived, how they died - and who killed them. Forensic scientists can unlock the mysteries of the past and help justice to be done using the messages left by a corpse, a crime scene or the faintest of human traces. Forensics uncovers the secrets of forensic medicine, drawing on interviews with top-level professionals, ground-breaking research and Val McDermid's own experience to lay bare the secrets of this fascinating science. And, along the way, she wonders at how maggots collected from a corpse can help determine time of death, how a DNA trace a millionth the size of a grain of salt can be used to convict a killer and how a team of young Argentine scientists led by a maverick American anthropologist uncovered the victims of a genocide.In her crime novels, Val McDermid has been solving complex crimes and confronting unimaginable evil for years. Now, she's looking at the people who do it for real, and real crime scenes. It's a journey that will take her to war zones, fire scenes and autopsy suites, and bring her into contact with extraordinary bravery and wickedness, as she traces the history of forensics from its earliest beginnings to the cutting-edge science of the modern day.

    He frames the lectures with four fundamental questions: What do we know when we are able to speak and understand a language? How is this knowledge acquired? How do we use this knowledge? What are the physical mechanisms involved in the representation, acquisition, and use of this knowledge? Starting from basic concepts, Chomsky sketches the present state of our answers to these questions and offers prospects for future research. Much of the discussion revolves around our understanding of basic human nature (that we are unique in being able to produce a rich, highly articulated, and complex language on the basis of quite rudimentary data), and it is here that Chomsky's ideas on language relate to his ideas on politics.The initial versions of these lectures were given at the Universidad Centroamericana in Managua, Nicaragua, in March 1986. A parallel set of lectures on contemporary political issues given at the same time has been published by South End Press under the title On Power and Ideology: The Managua Lectures.Language and Problems of Knowledge is sixteenth in the series Current Studies in Linguistics, edited by Jay Keyser.

    Yet it has also become clear that what truly separates developed from less developed countries is not just a gap in resources or output but a gap in knowledge. In fact, the pace at which developing countries grow is largely determined by the pace at which they close that gap.Therefore, how countries learn and become more productive is key to understanding how they grow and develop, especially over the long term. In Creating a Learning Society, Joseph E. Stiglitz and Bruce C. Greenwald spell out the implications of this insight for both economic theory and policy. Taking as a starting point Kenneth J. Arrow's 1962 paper "Learning by Doing," they explain why the production of knowledge differs from that of other goods and why market economies alone are typically not efficient in the production and transmission of knowledge. Closing knowledge gaps, or helping laggards learn, is central to growth and development.Combining technical economic analysis with accessible prose, Stiglitz and Greenwald provide new models of "endogenous growth," upending the received thinking about global policy and trade regimes. They show how well-designed government trade and industrial policies can help create a learning society; explain how poorly designed intellectual property regimes can retard learning; demonstrate how virtually every government policy has effects, both positive and negative, on learning; and they argue that policymakers need to be cognizant of these effects. They provocatively show why many standard policy prescriptions, especially associated with "neoliberal" doctrines focusing on static resource allocations, impede learning and explain why free trade may lead to stagnation, while broad based industrial protection and exchange rate interventions may bring benefits, not just to the industrial sector, but to the entire economy.The volume concludes with brief commentaries from Philippe Aghion and Michael Woodford, as well as from Nobel Laureates Kenneth Arrow and Robert Solow.

    But after she emerges from her egg, the treacherous waters are her goal. Swimming through the swirling waves and dodging larger sea creatures, she finds a resting place deep below. There she waits, until she grows into the majestic sea turtle that returns to the sand to lay her eggs and begin the cycle again.This journey of a small creature in the oceanic world of the dinosaurs is a perfect mix of scientific integrity and dramatic storytelling.

    Some old-time scientists thought that because they were so big, all they could do was float in water. Boy, were they wrong! Even today, once-common notions about dinosaurs are being revised as new discoveries are made. This lively book about the perennially popular subject of dinosaurs offers fascinating insight into how certain theories were formed, and then how those theories were proved or disproved. It demonstrates that scientific thought is as creative as it is logical and invites budding scientists to come up with their own ideas.
