How Fast Did T. rex Run? - David Hone - Bog - Princeton University Press - Plusbog.dk

How Fast Did T. rex Run? - David Hone - Bog - Princeton University Press - Plusbog.dk

The revolution in science that is transforming our understanding of dinosaursIn just the past twenty years, we have learned more about dinosaurs than we did in the previous two centuries. This book describes the extraordinary advances in palaeontology that are beginning to solve many of the mysteries surrounding these marvelous prehistoric creatures, including their mating habits, ways of communicating, skin color, migration patterns, and extinction. How did dinosaurs rear their young? What did they eat? What did T. rex actually do with those tiny arms? David Hone draws on his own discoveries at the forefront of dinosaur science to illuminate these and other questions.Each chapter in this lively and informative book covers a key topic in dinosaur science, such as origins, diversity, evolution, habitats, anatomy, behaviour, ecology and dinosaur descendantsthe birds. For each topic, Hone discusses the history of what palaeontologists thought in the past, the new insights we are gleaning from recent fossil finds and the latest technologies and the gaps in our knowledge that still remain. He shares his own predictions about the research areas that may produce the next big ideas in dinosaur science and addresses the unknowns we may never solve.How Fast Did T. rex Run? reveals everything we now know about dinosaursand everything we don'tand charts thrilling new directions for tomorrow's generation of dinosaur scientists.

Hadrian and the Cities of the Roman Empire - Mary T. Boatwright - Bog - Princeton University Press - Plusbog.dk

Hadrian and the Cities of the Roman Empire - Mary T. Boatwright - Bog - Princeton University Press - Plusbog.dk

Cities throughout the Roman Empire flourished during the reign of Hadrian (A.D. 117–138), a phenomenon that not only strengthened and legitimized Roman dominion over its possessions but also revealed Hadrian as a masterful negotiator of power relationships. In this comprehensive investigation into the vibrant urban life that existed under Hadrian''s rule, Mary T. Boatwright focuses on the emperor''s direct interactions with Rome''s cities, exploring the many benefactions for which he was celebrated on coins and in literary works and inscriptions. Although such evidence is often as imprecise as it is laudatory, its collective analysis, undertaken for the first time together with all other related material, reveals that over 130 cities received at least one benefaction directly from Hadrian. The benefactions, mediated by members of the empire''s municipal elite, touched all aspects of urban life; they included imperial patronage of temples and hero tombs, engineering projects, promotion of athletic and cultural competitions, settlement of boundary disputes, and remission of taxes.Even as he manifested imperial benevolence, Hadrian reaffirmed the self-sufficiency and traditions of cities from Spain to Syria, the major exception being his harsh treatment of Jerusalem, which sparked the Third Jewish Revolt. Overall, the assembled evidence points to Hadrian''s recognition of imperial munificence to cities as essential to the peace and prosperity of the empire. Boatwright''s treatment of Hadrian and Rome''s cities is unique in that it encompasses events throughout the empire, drawing insights from archaeology and art history as well as literature, economy, and religion.

When Is True Belief Knowledge? - Richard Foley - Bog - Princeton University Press - Plusbog.dk

Homogeneous Relativistic Cosmologies - Lawrence C. Shepley - Bog - Princeton University Press - Plusbog.dk

Homogeneous Relativistic Cosmologies - Lawrence C. Shepley - Bog - Princeton University Press - Plusbog.dk

Addressing a variety of theoretical cosmological problems, and emphasizing a mathematical approach, this volume nicely complements Peebles'' Physical Cosmology (Princeton Series in Physics, 1971). Ryan and Shepley have concentrated on the structure of models of the universe. By using a modern terminology that emphasizes the operator nature of vectors and tensors, as opposed to their components in a particular coordinate system, the authors develop modern tensor analysis to the point where it can be applied to general relativistic cosmology. They then use it to describe homogeneous cosmologies in considerable detail. Both students and researchers are likely to find these techniques especially useful.Among their subjects are: spaces with groups of motions; singularities; Taub-NUT-Misner space; Bianchitype models; Hamiltonian cosmology; and perturbations in anisotropic models. A brief section on observations is also included, as is a complete bibliography. A final section presents graded exercises that underscore the potential yet unrealized in this area of study.Originally published in 1975.The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

The Importance of Species - - Bog - Princeton University Press - Plusbog.dk

The Importance of Species - - Bog - Princeton University Press - Plusbog.dk

A great many species are threatened by the expanding human population. Though the public generally favors environmental protection, conservation does not come without sacrifice and cost. Many decision makers wonder if every species is worth the trouble. Of what consequence would the extinction of, say, spotted owls or snail darters be? Are some species expendable? Given the reality of limited money for conservation efforts, there is a compelling need for scientists to help conservation practitioners set priorities and identify species most in need of urgent attention. Ecology should be capable of providing guidance that goes beyond the obvious impulse to protect economically valuable species (salmon) or aesthetically appealing ones (snow leopards). Although some recent books have considered the ecosystem services provided by biodiversity as an aggregate property, this is the first to focus on the value of particular species. It provides the scientific approaches and analyses available for asking what we can expect from losing (or gaining) species. The contributors are outstanding ecologists, theoreticians, and evolutionary biologists who gathered for a symposium honoring Robert T. Paine, the community ecologist who experimentally demonstrated that a single predator species can act as a keystone species whose removal dramatically alters entire ecosystem communities. They build on Paine''s work here by exploring whether we can identify species that play key roles in ecosystems before they are lost forever. These are some of our finest ecologists asking some of our hardest questions. They are, in addition to the editors, S.E.B. Abella, G. C. Chang, D. Doak, A. L. Downing, W. T. Edmondson, A. S.
