This volume explores the varieties of relationships formed between science and civil society, at both the conceptual and institutional levels, since the late seventeenth century. It brings together general historians and historians of science with different national perspectives to confront the various ways sin which science and civil society have shaped one another in different times and places. How, when, and why did science become intertwined in the network of voluntary associations, professional groups and other institutions we understand as comprising "civil society"? How has science affected the ideology of civil society and thus the legitimacy of political authority in historical contexts as different as late eighteenth-century America, mid nineteenth-century Germany, and early twentieth-century China? How have scientists made use of the ideological links between science and civil political discourse to further their own professional ends? In contrast to much recent writing on civil society, this volume does not aim at making normative pronouncements about the role of civil society in promoting democratic polities, nor does it attempt to weigh the role of science in democracy. Instead, the essays examine how the fruitful interplay of beliefs concerning science and civil society has worked to legitimize the institutional forms of civil society and naturalize its ideologies, while at the same time giving to science its overwhelmingly powerful role in public life.

Sci-fi makes it look so easy. Receive a distress call from Alpha Centauri? No problem: punch the warp drive and you're there in minutes. Facing a catastrophe that can't be averted? Just pop back in the timestream and stop it before it starts. But for those of us not lucky enough to live in a science-fictional universe, are these ideas merely flights of fancy—or could it really be possible to travel through time or take shortcuts between stars?

Cutting-edge physics may not be able to answer those questions yet, but it does offer up some tantalizing possibilities. In Time Travel and Warp Drives, Allen Everett and Thomas A. Roman take readers on a clear, concise tour of our current understanding of the nature of time and space—and whether or not we might be able to bend them to our will. Using no math beyond high school algebra, the authors lay out an approachable explanation of Einstein's special relativity, then move through the fundamental differences between traveling forward and backward in time and the surprising theoretical connection between going back in time and traveling faster than the speed of light. They survey a variety of possible time machines and warp drives, including wormholes and warp bubbles, and, in a dizzyingly creative chapter, imagine the paradoxes that could plague a world where time travel was possible—killing your own grandfather is only one of them!

Written with a light touch and an irrepressible love of the fun of sci-fi scenarios—but firmly rooted in the most up-to-date science, Time Travel and Warp Drives will be a delightful discovery for any science buff or armchair chrononaut.
