How well we understand science affects almost every aspect of our personal and civic lives: our health, our understanding of the news, how and whether we vote, and our interaction with the environment.
Science can make a positive impact on people's lives. In some cases it can save lives. Remedies for many of the challenges that face our world will be developed by researchers who have devoted their lives to the pursuit of science.
