FROM THE PUBLISHER
"If our society is the most technologically sophisticated on Earth, then why can't we protect ourselves from terrorists and other threats to our safety and security?" The characters in these pages, from scientists and engineers to academics, entrepreneurs, and emergency workers, take us into a world of inquiry and discovery. Their stories reveal where our greatest vulnerabilities lie and where our best hope deservedly shines through. They show why the systems we rely on to protect ourselves can also be exploited by others to create catastrophe - and what we can do to outsmart the terrorists. We have ample proof that terrorists will go to great lengths to understand how our technologies can be put to destructive use. Now it's time to ask ourselves a question: Are we willing to let them keep beating us at our own game? For the innovators in these pages, the answer is no.
