Field Guide to the Grasses of Oregon and Washington - Barbara L. Wilson - Bog - Oregon State University - Plusbog.dk

Field Guide to the Grasses of Oregon and Washington - Barbara L. Wilson - Bog - Oregon State University - Plusbog.dk

As the comprehensive reference for 394 species, subspecies, and varieties of grasses, Field Guide to the Grasses of Oregon and Washington has become the definitive identification resource for amateurs and professionals alike throughout the region. With 18 additional species, updated names, new keys, and improved photos and maps, the second edition provides an in-depth and refreshed treatment of both native and introduced grasses that grow wild in Oregon and Washington and their neighboring states and provinces. This guide covers the entire spectrum of grasses, from weedy invaders to rare native species. It shows how grasses are valued for habitat restoration in numerous environments—from wetlands to deserts, and from sea level to alpine. Field Guide to the Grasses of Oregon and Washington provides identification keys, species descriptions, photographs of each species (both in the field and through a microscope), habitats, and range maps. Users will especially appreciate the labeled macrophotographs that illustrate hard-to-see diagnostic features. Biologists, land managers, botanists, and consultants, as well as plant professionals, home gardeners, and amateur plant enthusiasts, will find this guide an indispensable reference for identifying all the grasses encountered in the diverse habitats of Oregon and Washington.

Oregon and the Collapse of Illahee - Gray H. Whaley - Bog - The University of North Carolina Press - Plusbog.dk

Oregon and the Collapse of Illahee - Gray H. Whaley - Bog - The University of North Carolina Press - Plusbog.dk

Modern western Oregon was a crucial site of imperial competition in North America during the formative decades of the United States. In this book, Gray Whaley examines relations among newcomers and between newcomers and Native peoples--focusing on political sovereignty, religion, trade, sexuality, and the land--from initial encounters to Oregon''s statehood. He emphasizes Native perspectives, using the Chinook word Illahee (homeland) to refer to the indigenous world he examines. Whaley argues that the process of Oregon''s founding is best understood as a contest between the British Empire and a nascent American one, with Oregon''s Native people and their lands at the heart of the conflict. He identifies race, republicanism, liberal economics, and violence as the key ideological and practical components of American settler-colonialism. Native peoples faced capriciousness, demographic collapse, and attempted genocide, but they fought to preserve Illahee even as external forces caused the collapse of their world. Whaley''s analysis compellingly challenges standard accounts of the quintessential antebellum "Promised Land."

Seeing Color - - Bog - University Press of America - Plusbog.dk

Seeing Color - - Bog - University Press of America - Plusbog.dk

Indigenous peoples and racial minorities have lived and thrived in Oregon for centuries. Their legacy is interwoven with the state''s history and culture even as they continue to struggle with prejudice, environmental pressures, shrinking state revenues, the effects of globalization, and the changing dynamics of the state economy. Current U.S. immigration policy and the forces of globalization have played a critical role in creating a dynamic process named the ''browning of Oregon.'' This anthology brings together a group of noted multidisciplinary scholars, who explore the rich and varied experiences of Oregon''s native communities and racial minorities. Anchored in a ''power relations'' perspective, the book has been organized around several key historical themes, including: the foundation of ethnic communities; civil rights; social justice; ethnicity and labor; and various forms of cultural traditions. As disparate as they seem in style and topic, this collection of essays highlight the distinctive experiences of Oregon''s people of color and communicates the broader interlocking categories of social identity. The book is essential reading for students, teachers, and the general public interested in contemporary racial politics.

The Geometry of Special Relativity - Tevian (oregon State University Dray - Bog - Taylor & Francis Ltd - Plusbog.dk

The Geometry of Special Relativity - Tevian (oregon State University Dray - Bog - Taylor & Francis Ltd - Plusbog.dk

This unique book presents a particularly beautiful way of looking at special relativity. The author encourages students to see beyond the formulas to the deeper structure. The unification of space and time introduced by Einstein’s special theory of relativity is one of the cornerstones of the modern scientific description of the universe. Yet the unification is counterintuitive because we perceive time very differently from space. Even in relativity, time is not just another dimension, it is one with different properties The book treats the geometry of hyperbolas as the key to understanding special relativity. The author simplifies the formulas and emphasizes their geometric content. Many important relations, including the famous relativistic addition formula for velocities, then follow directly from the appropriate (hyperbolic) trigonometric addition formulas. Prior mastery of (ordinary) trigonometry is sufficient for most of the material presented, although occasional use is made of elementary differential calculus, and the chapter on electromagnetism assumes some more advanced knowledge. Changes to the Second Edition - - The treatment of Minkowski space and spacetime diagrams has been expanded. - - - Several new topics have been added, including a geometric derivation of Lorentz transformations, a discussion of three-dimensional spacetime diagrams, and a brief geometric description of "area" and how it can be used to measure time and distance. - - - Minor notational changes were made to avoid conflict with existing usage in the literature. - - - Table of Contents - - Preface 1.

His research lies at the interface between mathematics and physics, involving differential geometry and general relativity, as well as nonassociative algebra and particle physics; he also studies student understanding of "middle-division" mathematics and physics content. Educated at MIT and Berkeley, he held postdoctoral positions in both mathematics and physics in several countries prior to coming to OSU in 1988. Professor Dray is a Fellow of the American Physical Society for his work in relativity, and an award-winning teacher.
