Unscientific America: How Scientific Illiteracy Threatens our Future
A plea for enhanced scientific literacy, Unscientific America urges those who care about the place of science in our society to take unprecedented action. We must begin to train a small army of ambassadors who can translate science's message and make it relevant to the media, to politicians, and to the public in the broadest sense. An impassioned call to arms worthy of Snow's original manifesto, this book lays the groundwork for reintegrating science into the public discourse--before it's too late.
