Miller looks out across America, which he can almost do from his 18th-floor office at Northwestern University Medical School in Chicago, he sees a landscape of haves and have-nots — in terms not of money, but of knowledge. Dr. Miller, 63, a political scientist who directs the Center for Biomedical Communications at the medical school, studies how much Americans know about science and what they think about it. His findings are not encouraging. Dr. Miller's data reveal some yawning gaps in basic knowledge. American adults in general do not understand what molecules are (other than that they are really small). Fewer than a third can identify DNA as a key to heredity. Only about 10 percent know what radiation is. One adult American in five thinks the Sun revolves around the Earth, an idea science had abandoned by the 17th century."
