How is society influenced by engineering and technology? How in turn does society shape engineering and technology? This book from the National Academy of Engineering explores ways in which technology and society form inseparable elements in a complex sociotechnical system. The essays in this volume are based on the proposition that many forces move and shape engineering, technology, culture, and society. Six specialists both inside and outside the field of engineering offer views on how engineering responds to society's needs and how social forces shape what engineers do and what they can achieve.
