Gravity is the weakest of the natural forces and yet it dominates our lives. We know how to make use of its properties and how to overcome it. But we can't control it. To do that we must be able to generate and control gravity's hidden companion force field, called gravitomagnetism. Mass is the source of gravity fields.
This book describes an exciting, but unfinished scientific adventure story. It tells of the epic struggle by scientists to wrest the secrets from nature of how to control the force of electromagnetism and how to control aerodynamic forces. Control of the force of gravity has yet to be achieved. Analogies suggest where a breakthrough might be made. Greenglow & the search for gravity control follows the attempts mankind has made over the years to understand gravity as well as looking at more recent experiments to control it. The book is written by an engineer, who worked in the aerospace industry, and who persuaded BAE Systems to sponsor Project Greenglow, a small research programme aimed at i...
Logically organized with comprehensive coverage, this newly revised third edition prepares you to choose the right orthopedic tests, accurately assess any patient, and arrive at a clear diagnosis. Trusted for both its depth of coverage and its accessible, accurate information, it features gamuts, clinical pearls, and cross-reference tables for quick and easy reference. Now in brilliant full color, with all new photos of every test, it's even more visually appealing, and illustrates common conditions and procedural tests more effectively than ever before. This edition offers a fresh look at testing for orthopedic conditions, with detailed text that explains the key moves of each test, its alt...
Ronald Evans describes and interprets the continuing battles over the purposes, content, methods, and theorectical foundations of the social studies curriculum. This facinating volume: addresses the failure of social studies to reach its potential for dynamic teaching because of a lack of consensus in the field; links the ever-changing rhetoric and policy decisions to their influence on classroom practice; and helps to clarify the meaning, direction, and purposes of social studies instruction in schools.

Over the course of the past decade and a half, we, Samuel Totten and Jon E. Pedersen, have co-edited a series of books on teaching and learning about social issues. Our goal has been to build a series that would broadly represent the work that has been undertaken over the past 110 plus years related to the field of teaching and learning about social issues. As we created and added to the series (see for example: Addressing Social Issues in the Classroom and Beyond: The Pedagogical Efforts of Pioneers in the Field; Researching and Teaching Social Issues: The Personal Stories and Pedagogical Efforts of Professors of Education; Teaching and Studying Social Issues: Major Programs and Approaches)...
