Sand
"I have learned more about, and become more fascinated with sand from reading this book than I have from studying beaches for thirty-five years! An amazing story."--Reinhard E. Flick, Scripps Institution of Oceanography, University of California, San Diego "A masterful, entertaining and accessible treatise on the complex world of common sand."--Bruce M. Pavlik, author of The California Deserts "To do justice to this formidable and glorious subject, you need not only to be in love with it, but also to possess tremendous breadth of knowledge, have the eyes of a poet, scientist and geographer, and be intrepid enough to have seen the deserts of the world at first hand. Fortunately, Michael Wella...
Mechanics of Deformation and Flow of Particulate Materials
Proceedings of a Symposium sponsored by the Engineering Mechanics Division of ASCE (Committee on Properties of Materials and Committee on Fluid Mechanics) and the Applied Mechanics Division of American Society of Mechanical Engineers) (Committee on Geomechanics) Evanston, IL, June 29-July 2, 1997. Presenting a collection of recent advances in the areas of granular solids and granular fluids, these proceedings examine a variety of theoretical approaches including micromechanical methods, with the consideration of particle interactions, and conventional continuum mechanics methods. Complementary, computational, and experimental techniques that have been developed that study phenomena ranging from particle-level to bulk behavior are also covered.
Under Prairie Skies
In Under Prairie Skies, C. Thomas Shay asks and answers the question, What role did plants play in the lives of early inhabitants of the northern Great Plains? Since humans arrived at the end of the Ice Age, plants played important roles as Native peoples learned which were valuable foods, which held medicinal value, and which were best for crafts. Incorporating Native voices, ethnobotanical studies, personal stories, and research techniques, Under Prairie Skies shows how, since the end of the Ice Age, plants have held a central place in the lives of Native peoples. Eventually some groups cultivated seed-bearing annuals and, later, fields of maize and other crops. Throughout history, their lives became linked with the land, both materially and spiritually.
The Desert
From endless sand dunes and prickly cacti to shimmering mirages and green oases, deserts evoke contradictory images in us. They are lands of desolation, but also of romance, of blistering Mojave heat and biting Gobi cold. Covering a quarter of the earth’s land mass and providing a home to half a billion people, they are both a physical reality and landscapes of the mind. The idea of the desert has long captured Western imagination, put on display in films and literature, but these portrayals often fail to capture the true scope and diversity of the people living there. Bridging the scientific and cultural gaps between perception and reality, The Desert celebrates our fascination with these...
